Fused Magnesia Crystal


Description

Fused magnesia crystal are made by high purity caustic calcined magnesite through electro - fusing , a part of SiO2 turns back to SiO and runs out , another part of SiO2, moves to the surface because of the huge difference in the specific gravity with MgO, after this process, the magnesite become pure and the crystal become strong and big. It has high purity, compact structure, strong slag resistance and good thermal shock resistance. It is the first choice for making various basic refractory materials.
