钼及其合金具有熔点高,高温强度大,热膨胀系数小,化学稳定性好和耐腐蚀等优良特性,故在钢铁、机械、玻璃、陶瓷、电子、化工、军工、宇航和原子能等领域有广泛应用,但80％左右是作为合金添加剂用于钢铁工业。我国于1939年在东北辽西杨家杖子矿发现钼资源,1940年生产出46吨钼精矿,从此中国有了钼。解放前我国钼工业规模很小,基本上没有钼加工工业。解放后经过48年来的建设和技术改造,我国钼工业已从小到大, Molybdenum and its alloys have the advantages of high melting point, high temperature strength, small thermal expansion coefficient, good chemical stability and corrosion resistance. Therefore, molybdenum and its alloys are widely used in the fields of iron and steel, machinery, glass, ceramics, electronics, chemicals, military, aerospace and atomic energy Application, but about 80% is used as an alloy additive for the steel industry. In 1939, China found molybdenum resources in Yangjiazhangzi Mine in Liaoxi, northeast China, and produced 46 tons of molybdenum concentrate in 1940, from which China had molybdenum. Before the liberation of China’s molybdenum industry is small, basically no molybdenum processing industry. After the liberation of 48 years of construction and technological innovation, China’s molybdenum industry has grown from small to large,
