1) industry
The 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 industry
The high quality of fused magnesia can be used to produce electronic products in insulating materials.
