Large crystal fused magnesia is produced by melting selected high purity light magnesia powder in arc furnace. The product has high purity, dense crystallization, strong slag resistance and good
thermal shock stability.
Physical properties：
High purity: Usually the MgO content is as high as 96%-99% or more, and the impurity content is extremely low, which helps to improve the high temperature resistance and corrosion resistance
of refractory materials.
Density and low porosity: The large crystal structure generated by high temperature melting has high density and low porosity, which improves the resistance to slag erosion.
High melting point: The melting point is as high as 2800°C or more, suitable for use in extremely high temperature environments.
Excellent mechanical strength: Maintains stable strength and hardness in high temperature environments, and is not easy to deform or damage.
Chemical properties：
Chemical corrosion resistance: Strong resistance to acidic and alkaline slag, suitable for high alkalinity slag environment in the steel industry.
Good thermal shock stability: Able to withstand rapid changes in temperature, not prone to peeling or cracking.
High thermal conductivity: Has high thermal conductivity in high temperature environments, suitable for applications requiring heat exchange.
Application of Large Crystal Fused Magnesia:
Large crystal fused magnesia is an important raw material for making high-grade magnesia carbon brick and amorphous refractory, and is also an excellent high temperature electrical insulation
material.
