Large crystal fused magnesia

Product Features:

The large crystal fused magnesia is obtained by melting a selected high-purity light-burning magnesia powder in an EAF.

High purity, large grain size, high melting point and compact structure. Produced refractory products with good slag resistance, thermal shock stability and high temperature modulus of rupture.

Main application:

Large crystal fused magnesia is a high-quality alkaline refractory raw material for the manufacture of shaped refractory bricks and unshaped refractory for steelmaking, it can be used as a filler for thermoelectricity.Even and thermal insulation materials can also be used for ceramic raw materials and sintering aids as well as metallurgy, building materials, chemicals national defense, medical equipment and so on.
