Strong Anti-Corrosion Industrial Magnesium Oxide for Electrical Applications

Product Description

 

1.Caustic Calcined Magnsite:
Magnesite, or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg2+ ions and O2−ions held together by ionic bonding. Magnesium hydroxide forms in the presence of water (MgO + H2O → Mg(OH)2, but it can be reversed by heating it to separate moisture. Caustic Calcined Magnesite is made from magnesite by 950-1100 degree heating.

2. DBM:
Dead Burned Magnesia is a typical refractory material. It is made from magnesia from 1200 to 1700°C. It has strong corrosion resistance to various molten metals. Dead Burned Magnesite as metallurgical industrial refractory, used for manufacturing magnesia brick, electric furnace bottom and lining, etc.

3. FM:
Fused magnesite is produced by raw magnesite ore in an electric arc furnace. Fire resistance up to 2200°C. The product has high purity, large particle size, fine structure and excellent thermal stability. It can be used for fire resistance, steel, etc.

4. CFM:
Crystal Fused magnesite is produced by caustic calcined magnesite in an electric arc furnace. It can be used for fire resistance, electronic chips, etc.
