The cerium oxide powder is a light yellow or brown powder. Its density was 7.13g/cm3, a melting point of 2397 ° C. It is insoluble in water and alkali, but slightly soluble in acid. At a temperature of 2000 ° C and pressure of 15Mpa, we can use the hydrogen reduction of cerium oxide, cerium oxide. When the temperature is between 2000 to 2007, the Liberal ℃, pressure 5MPA, cerium oxide yellow and red, maybe pink, its performance as polishing materials. But it is mainly used as a glass decolorizing agent, glass polishing powder, it is also prepared a raw material of cerium metal, high purity cerium oxide is also used for the production of luminescent materials. Insoluble in water, but can be dissolved in acid. Bleach, it not only can be used for glass, advanced polishing powder as a clarifying agent, is also used in ceramic electrical, chemical, and other industries.
The History of the Development of Cerium Oxide Powder
With the development of rare earth industry in the 1930s, first as a polishing powder glass polishing rare earth oxides in Europe. Rare earth polishing powder in World War II, soon succeeded in polishing precision optical instruments. Abroad 60 years ago to start the production of rare earth polishing powder in the 1990s, it has formed more than 30 kinds of products in a variety of standardized series. Currently, the major domestic brands chute brand cerium oxide powder and arrogant beauty brand cerium oxide polishing powder. 15 foreign rare earth polishing powder manufacturers (annual production capacity is 200 tons or more. The annual production capacity of France Rhodia is over 2200 tons, it is the world's largest rare earth polishing powder manufacturer. In 1968, China's first successful development of rare earth polishing powder chemical plant in Shanghai, cerium oxide manufacturers in China more than 14 (annual production capacity of more than 30 tons), compared with foreign countries, there is still much gap.
The Application of Cerium Oxide Powder
As a rare earth manufacturer says, cerium rare earth polishing powder has better chemical and physical properties, so that it has a polishing of a wide range of applications in the industrial products, such as in the device of the various optical glass, television picture tubes, an optical lens, a CRT, flat glass polishing a semiconductor wafer and precision metal products, such as. Cerium rare earth polishing powder is mainly applied in high-speed precision optical lens polishing. Of the cerium rare earth polishing powder, high-speed optical instrument is mainly applied to the polishing of moderate precision small and medium-sized spherical lens. Domestic use polishing powder dosage still need to be to continue to develop new uses in the future. The low cerium oxide rare earth polishing powder is suitable for television picture tubes, eyeglass lenses and flat glass polishing. Therefore, the purpose of cerium oxide production is to grasp the opportunity to develop in the glass deep processing industry.
www.rareearth-china.com is committed to the production,research and development, sales ceramic raw materials and cerium oxides and other rare earthe materials for chemical industry, as well as chemical raw materials for glass-ceramic.

Characteristics and Use of Aluminum Honeycomb
Decline of China Rare Earth Exports
Under the mainland rare earth resources protection policy, the rare earth export has a substantial reduction and the prices continued to rise. According to statistical data, in February of this year, China's rare earth average export price level has been exceeded $ 100,000 per ton (approximately HK $ 7.8 million), compared with a year ago, it surged 9 times. In the past few months, according to data released by the General Administration of Customs, China's rare earth exports average price every month is up to $ 10,000 per ton, and the rare earth manufacturer said that it is very hard to do export business this year. From since the beginning of this year, China's exports of rare earth price increase is particularly alarming, the data shows that single in the month of February, the average price of Chinese exports of rare earth is up to $ 34,000 per ton. View of China's introduction of restrictions of rare earth export policy, the United States, Canada and Australia and other countries have increased the domestic rare earth resources exploration and development efforts to deal with the situation to reduce the supply and prices.
China Rare Earth Export Prices
The so-called rare earth is the general term of 17 kinds of special metal elements. China supplies about 97% of the world's rare earth. The applications of rare earth cover iPods and wind turbines, smart phones, electric car motors and high-tech industrial equipment. In 2003, the Chinese government released the quota system of rare earth; in 2005, the Chinese government canceled a rare earth export tax rebate, and the compression enterprise quota of export quotas. In April 2006, the Chinese Ministry of Land and Resources to stop issuing permits mining of rare, from November 1 of the same year, the Chinese government imposed export tariffs on commodities such as rare earth and ferrosilicon. The quota system is decided according to the amount of 80% of the worldwide export quotas. All these policies show that Chinese government is limiting the exploration of domestic rare earth. This makes a barrier for the rare earth supplier in China. It is much more difficult for them in foreign trade.
Western Countries Depend on China Rare Earths
The face of China's rare earth export policy adjustments, the western countries and Japan and the United States are consistent with the shelling of China, they think China is in violation of WTO rules. Krugman, the Nobel laureate in economics published in the New York Times from rare earth export the rogue economy" as the culmination. The Beijing News Posting questioned "Krugman, on what basis shelling of China's rare earth export restrictions policy? The reason is that China accounts for only 30% of the world's rare earth resources, why should bear 97% of consumption? U.S. rare earth reserves ranks the third in the world, why stop mining in favor of imports from China and other places? Why the United States can protect its own environment, but at the expense of China's environment? In fact, it is not the exploitation of rare earth, but the United States has long been cheap Chinese dumping to the defeated. Originally, the U.S. rare earth mining accounts for 30%, was mothballed in 2001, the largest rare earth mine in Mountain Pass mine Since then, the United States is no longer has production of rare earth, and more are no longer exported, but it imports in large quantities from China instead.

The Current Situation of Rare Earth Metal in the World
Wide Applications of Rare Earth Metal
Rare earth metals, a collection of 17 metallic elements of similar properties and structures, play essential roles during manufacturing various wide ranges of high tech applications. Moreover, Rare earth metals offered by the rare earth manufacturer and rare earth supplier are the vital components for high tech products production, such as phones and hybrid cars. Besides that, they are also applied in computer discs, guided missiles, TV screens and microphones, photo-voltaic cells, energy-efficient lighting, wind power and so on.
The Advantage of Rare Earth Metal in China
The essential issue is the fact that rare earth metals from rare earth manufacturer and rare earth supplier are not found in economically viable concentrations in any one place. They are spread out across the planet and are typically extracted as a by-product of other mining activities. Because of this, the cost of procuring them may be prohibitively high. Over the past decade or more, the only nation mining rare earth metals in great quantities has been China. Therefore, China has become a stranglehold on the marketplace, controlling more than 95 % in the world trade, which include nearly two valuable rare earths - Dysprosium and Neodymium. With rising domestic demand, and ostensibly to protect the environment through limiting mining operations, China even imposed export restrictions lately, leading foreign producers and governments into somewhat of a panic. Other nations do have rare earths metal deposits, but China's low-cost labour and not too tight environmental restrictions have made it an advantage. But this dependence has made people to look for other economically viable sources. By now, geologists have searched one million metric tons of these valuable metals, such as lanthanum, cerium and neodymium, which could be adequate to satisfy the world's demands for ten more years depending on current consumption.
Increasing demands of Rare Earth Metal
Therefore, in the foreseeable future, China’s virtual monopoly with the rare earth metals supply from rare earth manufacturer and rare earth supplier will continue to remain as the rare minerals, with increasing demands around the world with growing prices. For those who are meant to find a professional services to enable them to make wise and profitable choices before decide to invest, our company would be ready to offer you various services and products.

China Rare Earth Status
China Rare Earths Stocks
Some experts point out that now China’s rare earth stocks are decreasing year by year, the total estimated stocks can only be maintained for 20 years. The reserves of China's rare earth in the year 1996 to 2009 fell 37 percent, only remained 27 million tons. At current production rates, the middle level type and the key level type rare earth stocks in China can only last 15-20 years, in the year 2040 to 2050, we must import rare earth from abroad to meet domestic demands. China is not the only country with rare earth in the world, but in the past few years it always assumes the role of the world's rare earth manufacturer, the results is that we have to pay the cost of destruction of the natural environment and consume our own resources.
Rare Earth Investing in Broad
Japan began to look around the globe for the alternative rare earth supplier to replace China's rare earth supply source. Tokyo plans to invest $ 1.2 billion to improve the supply of rare earth conditions. Japan has reached an agreement with Mongolia in a hurry to development the rare earth resources in Mongolia from this month. Another rare earth consuming countries South Korea also has similar plans. Earlier this month, South Korea announced it would invest $ 15 million to reserve 1200 tons of rare earth in 2016.
Cheap Export Rare Earth Prices
The current price of 99.9% purity cerium oxide is 18 yuan / kg, the highest price is sold for 30 yuan / kg in the past, sometimes the price of rare earth is even cheaper than the pork. Take the price of neodymium oxide as an example, which should be sold for at least 110-120 yuan / kg, only in this way, it is able to compensate for the loss of lanthanum, cerium, yttrium, and part of the heavy rare earth elements. The consensus of the Rare Earth Industry Association is: the average export price of 30 kinds of rare earth products is increased though, but the price is only the surface scenery, since ever from May of last year, the state canceled the export tax rebate of two rare earths, and at the same time, a large number of export quotas enterprises are compressed, if translation of these two factors, and coupled with the raw and supplementary materials such as water, electricity, transport prices and other factors, China rare earth prices still hovering at the bottom. From the year 1990 to 2005, Chinese rare earth export volume grew nearly 10 times, but the average price was down to 64% of the original price. In the case of the world's high-tech electronics, laser, communications, superconducting materials exponentially needs of China's rare earth prices has not gone up. Some representatives from the rare earth enterprises said the rare earth profits is generally between 1-5% according to the current price. The highest is up to about 5% , the selling price is just the soil price.
