is made by using special-A
grade natural magnesite ore or high-purity calcined magnesite
particles in an electric arc furnace. It is characterized by high
purity, large crystal size, dense structure, strong resistance to
erosion, and good thermal shock stability. It is an excellent
high-temperature electrical insulation material as well as one of the
important material in making high grade magnesia bricks, magnesia
carbon bricks and monolithic refractories.
