Magnesium Oxide

Molecular Formula: MgO

Molecular Weight: 40.3

Appearance:Transparent glass sheet or white crystalline powder

CAS No.:10124-56-8

HS:251990

Property:

White amorphous powder, odourless. Melting point:2800.Boiling point:3600

It can soluble in acid or ammonium salt solution, insoluble in water and ethanol.In the air it can gradually build basic magnesium carbonate after absorbing moisture and carbon dioxide. It is the raw material of electronic products and advanced fire-resistant products.

Application:

1.Fire retardant used for chemical fiber and plastics trades.

2.High-temperature dehydrating agent used for the production of silicon steel sheet, high-grade ceramic material, electronic industry material, adhesive and additive in the chemical raw material.

3.High-frequency magnetic-rod antenna, magnetic device filler, insulating material filler and various carriers used in radio industry.

4.Refractory fiber and refractory material, magnesite-chrome brick, filler for refractory coating, refractory and insulating instrument, electricity, cable, optical material, material for steel-smelting furnace and other high- temperature.
