In 1782, Sweden's Elm, emphasized the use of linseed oil mixture confined burning charcoal and molybdic acid, molybdenum obtained. 

 

  Molybdenum is a rare metal, is closer to the nature of molybdenum with tungsten, having a melting point of about 2620 ℃, has a high temperature strength at elevated temperatures. Above 1000 ℃, molybdenum strength is the highest, it is very useful for high temperature structural materials. Because of the high melting point of molybdenum, electrical and thermal conductivity, and can be used as high temperature furnace heating elements and heat reflective material. Molybdenum do with electric heating element operating temperature up to 1700 ℃. High conductivity of molybdenum are better than iron and nickel, the expansion coefficient of about 30% copper, and the expansion coefficient of electron tubes is almost the same as the special glass. Good corrosion resistance of molybdenum, tungsten is an acidic behind. In the metallurgical industry, molybdenum is an important additive: plus molybdenum alloy can improve the heat resistance, corrosion resistance, wear resistance, toughness and hardenability, etc., so it is very useful alloy elements. 

 

Molybdenum is a component of many enzymes, molybdenum deficiency can lead to tooth decay, kidney stones, Keshan disease, Kashin-Beck disease, esophageal cancer and other diseases. Humans and animals have a strong body of molybdenum in the stabilization mechanism, oral intake of molybdenum compounds are unlikely to cause poisoning.
