According to the website of the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology and the Ministry of Natural Resources jointly issued a notice on the release of the total amount of rare earth and tungsten mining, smelting and separation control indicators.
Vegetable oil is the most important food for the people. It is not only the most basic raw material for the food industry, but also an important raw material for industrial and agricultural production and national defense construction.
In recent years, researchers from the Massachusetts Institute of Technology and China have developed a capacity-type lithium battery containing molybdenum material, which has higher weight energy density and volumetric energy density than conventional commercial batteries.
Sintering of tungsten-based heavy alloys is an important part. The sintering process has a great influence on the density, grain size, segregation and microstructure of the alloy.
Due to its high strength, high melting point, corrosion resistance and wear resistance, molybdenum has been used in steel, chemical, electrical, pharmaceutical and agricultural fields. China is the country with the most abundant molybdenum resources in the world.
Tungsten is a rare high melting point metal in nature with a melting point of up to 3,410 ° C. It has high density, high hardness, high wear resistance, high electrical conductivity and high temperature strength.
Tungsten alloy weights have a long history of development. China has entered the heyday of bronze castings between 1700 and 1000 BC, and the process has reached a fairly high level. Europe also began producing counterweights around the eighth century.
Recently, the China Tungsten Industry Association held a symposium of leaders of tungsten enterprises (groups) in Ganzhou. The meeting unanimously agreed that the participating tungsten enterprises (groups) will jointly maintain the supply order of the tungsten raw material market.
