Molybdenum is a metal element. Mo, atomic number 42, is a metal in the VIB group.

Molybdenum has a density of 10.2g/cm cubed, a melting point of 2610℃ and a boiling point of 5560℃.Molybdenum is a silver-white metal, hard and tough, with high melting point, high thermal conductivity, and no oxidation reaction with air at room temperature.

As a transition element, it is easy to change its oxidation state, and the color of molybdenum ion will change with the change of oxidation state.Molybdenum is an essential trace element for human beings, animals and plants, and plays an important role in the growth, development and inheritance of human beings, animals and plants.

The average content of molybdenum in the earth's crust is 0.00011%. The global molybdenum reserves are about 11 million tons and the proved reserves are about 19.4 million tons.

Due to its advantages of high strength, high melting point, corrosion resistance and abrasion resistance, molybdenum is widely used in iron and steel, petroleum, chemical industry, electrical and electronic technology, medicine and agriculture.
