Product Details


Magnesia Refractory Brick Description

 

Magnesia Bricks are alkaline refractory materials. These products have over 90% magnesium oxide content and adopt periclase as the principal crystalline phase. Magnesia Bricks can be divided into two categories of Burnt Magnesia Bricks and Chemical Bonded Magnesite Brick. They have excellent performance of superior high temperature mechanical strength and volume stability. Magnesia Bricks can service in the high temperature of 1750℃. They are ideal products for glass furnace application.
