Our Magnesia Bricks are alkaline refractory materials. They have high percentage of magnesium oxide content and validate periclase as the principal crystalline phase. Magnesia Bricks splits into two classification of Burnt Magnesia Bricks and Chemical Bonded Magnesia Brick. They outstand superior temperature mechanical strength and volume stability. Magnesia Bricks can assist in high temperature of 1750℃. They are exemplar products for glass furnace application. Burnt Magnesia Bricks are excessively pure and have firing temperature as the direct contact with periclase crystalline grain. \ Chemical bonded magnesia brick is made of fused magnesite as the raw material.
