摘　　要：Molybdenum is a transitional metal in the periodic table of elements where it ranks in position 42 in the 5th period and group VI B.Having a high melting point of 2623℃,molybdenum belongs to the so-called refractory metals.Accordingly,as pure metal it finds many applications where high temperatures are encountered during operation,for example in furnaces.However,nearly 80%of all molybdenum produced every year by the world’s mining industry is used as addition to iron and steel alloys.Carbon and alloy steels account for 40%of molybdenum use,followed by stainless steels(23%),tool steels and castings(both around 8%).
