Scandium oxide (Sc2O3)

Scandium oxide (Sc2O3) is one of the most important scandium products.  Its physical and chemical properties and rare earth oxides (such as La2O3,Y2O3 and Lu2O3, etc.) are similar, so the production method used in production is very similar.  Sc2O3 can produce scandium metal (Sc), different salts (ScCl3,ScF3,ScI3,Sc2(C2O4)3, etc.) and products of various scandium alloys (Al-Sc, Al-Zr-SC series).  These scandium products have practical technical value and good economic effect.  Because Sc2O3 has some characteristics, so in aluminum alloy, electric light source, laser, catalyst, activator, ceramics and aerospace and other aspects have a good application, its development prospects are very broad.  

In the 1970s, China began to develop Sc2O3 products, and there are kilograms of products into the market.  In the 1980s, China's Sc2O3 production into the climax, output of 100 kg level above, mainly exported to Japan, the United States.  Since the 1990s, Russia has produced a large number of Sc2O3 products and thrown them into the international market at a low price, seriously impacting the production of scandium oxide in China, making Sc2O3 production at a low ebb, many production lines dismounted, making China's capacity and output in a state of shrinkage.  But in recent years, due to the development of China's SC-Al alloy and electric light source materials, promote the development of Sc2O3 industrial production.  China is rich in scandium resources.  It is reported that the industrial reserves of scandium around the world are about 2 million tons, and there are about 600,000 to 650,000 tons in China, accounting for about 30% of the world's total content
