After more than a year of trial and error , the Baotou Rare Earth Research Institute has successfully developed a non-toxic, environmentally friendly, and good long-term stability of the new rare earth PVC stabilizer. Currently in the test line is under construction , is expected to put into production that year .
At present , the domestic PVC production enterprises mainly use lead salt , stearic acid metal, organic tin stabilizers , among the most widely used lead salt stabilizer , but there are hazards such stabilizers environmental safety issues. Rare PVC stabilizer has a clear advantage in overall performance and cost , and environmental protection. The hospital engineer Zhang Xi introduced , accounting for 3.5% PVC stabilizer weight , and now the national production of 13 million tons per year PVC , and is still rising year by year , the imminent implementation of a comprehensive ban on the use of lead stabilizers on the urgent need of environmental protection , and efficient , cheap alternative. In addition, the main component of the rare earth lanthanum cerium stabilizer element content of about 10% , PVC terms of annual output 13 million tons per year to use 40,000 tons of elements lanthanum , cerium , which for digestion Baiyunebo lanthanum cerium element has surplus significance.

According to reports, Atomic Energy of Kazakhstan uranium production company as a state-owned enterprise intends to produce rare earth, rare earth ore and may consider buying from overseas. This incentive is to stimulate the rise in rare earth prices.
Kazakhstan has abundant natural resources , five times the size of France , and a population of only 17 million , the country eager to have a share in the business to make money in a similar rare .
"As for the rare earth , we are looking to get the issue tantalum and niobium ore from Africa, we are considering various regions of proved reserves ," Atomic Energy company responsible Vladimir Shkolnik said , and declined to provide further details.
He said the company is also considering the purchase of Atomic Energy of domestic rare earth ore development permit , "The market is huge, from Japan to Europe and Russia ."

The analysis of the mechanism of formation and deposition of pyrolytic carbon through and found only rare earth can promote pyrolysis of hydrocarbons carbon sink , and chlorine has also accelerated the dehydrogenation of hydrocarbons , halogen theoretically confirmed the French Atomic Energy Commission experts can increase the rate of pyrolytic carbon deposition experimental phenomena . These studies recognized by the National Natural Science Foundation of experts and lay a good foundation for the smooth implementation of the project and the subsequent declaration of the Natural Science Foundation of China .

U.S., EU and Japan in 2012 to the World Trade Organization (WTO) complaint , which means that the continent restrict exports of rare earths is a violation of WTO rules in practice . WTO has made a ruling on March 26, 2014 , ruling on the complaint of state benefits .
Although the United States , the EU and Japan in the WTO to win the round , but in fact the same time early in their appeal , have already begun trying to reduce dependence on the mainland rare , once rare because the continent as a military and diplomatic negotiations outside chips. Up to rare earth imports from mainland Japan, for example , has sought to diversify alternatives , such as rare earth ore imported from Australia, India, investment in the production of rare earth, even to replace other materials such as rare earth , therefore , in the world's rare earth monopoly position in the continent decreasing , also led to rare earth prices fall.
From 2014 rare earth export quota for mainland point of view , representing a decrease of approximately 30% in 2013 , mainly due to exports of rare earths in 2013 is lower than the actual amount of that year 's quota , the 2014 quotas are adjusted accordingly . Also, according to industry research of rare earth observation monthly price changes associated with the LED cerium rare earth metals, metal yttrium , terbium oxide , in March 2014 the price was reduced rates were 38.1% , 0%, 41.3% , if the 2012 compared highs , down as much as 52 to 83 percent , this display with LED phosphors past tense situations expensive now appear soothing .
