1.Products features: Commodity Name: Fused magnesiaMolecular Formula:MgO HS Code:2519.9010
Fused magnesia is produced from natural magnesite or high purity calcined magnesite grain, which is fused in arc furnaces. The product has high purity, crystal grain, compact structured, strong slag resistance and good thermal shock stability. It is a kind of excellent high temperature electrical insulation material and is also used to make high quality magnesite bricks, magnesia carbon brick and the important raw materials for amorphous refractory.

2.Product usage:
| (1)industryThe structure of fused magnesia is in tact, has good stability, high temperature resistance, strong corrosion resistance. It is the most important raw material of refractory used in the manufacturing of all kinds of magnesite brick, magnesium aluminum brick, ramming material and more. Fill burden material which contain more impurities, is used for paving steel furnace bases. |
| (2)the electronics industryThe high quality of fused magnesia can be used to produce electronic products in insulating materials. |
