Specification of Sodium Molybdate

SELL Sodium Molybdate

Molybdenum was one of the first metals discovered by modern chemists. Discovered in 1778 by Swedish chemist Carl Wilhelm Scheele. Molybdenum is a transition metal, so it places it in the middle of the periodic table, with atomic number 42. The periodic table itself is a chart that shows how chemical elements are related to one another. Molybdenum is hard, like silver metal with a very high melting point. Molybdenum is usually used to be a mixture with other metals. The mixture itself will have different properties from the first metal element, Molybdenum is usually often mixed with steel to increase strength, toughness, resistance to wear and corrosion, and the ability to harden steel.

The properties as follows

Molybdenum is a solid element, having a silvery-white metallic appearance. More often it looks like dark gray or black powder. The melting point is around 2,610 ° C (around 4,700 ° F) and the boiling point is 4,800 to 5,560 ° C (8,600 to 10,000 ° F). Its density is 10.28 grams per cubic centimeter.
