Name: Large Magnesium Chips
English Name: Magnesium
Molecular Formula: Mg
Molecular Weight: 24.31
CAS No: 7439-95-4

1. Product Description
Made of high-purity refined magnesium. It is a widely used magnesium product for Grignard reactions. It can also be used for desulfurization, purification and as a reducing agent.
Magnesium is a silvery-white metal of hexagonal crystal system.
Melting point: 648.5 ℃
Boiling point: 1107 ℃
Relative density: 1.74
Soluble in inorganic acids and ammonium salts; insoluble in cold water, chromic anhydride and alkalis. It reacts with hot water to produce magnesium hydroxide. It keeps metallic luster in dry air, while forming a gray oxide film by oxidation in humid air.
Magnesium powder and chips are flammable at room temperature and shall be handled with care. Massive magnesium is prone to oxidative combustion at high temperatures. Heat treatment and related operations shall be conducted under the protection of sulfur dioxide or sulfur hexafluoride atmosphere.

2. Applications
It is mainly used in four fields: magnesium alloy production, aluminum alloy production, steel desulfurization, aerospace and military industry. It is also applied in rare earth alloys, metal reduction, chemical industry and instrument manufacturing.
