Magnesia Brickis a kind of basic refractory with more than 90% magnesium oxide content, are made of periclase as the main crystal phase. Magnesia bricks can be divided into the sintered magnsite brick( also named as burnt magnesite brick) and chemical bonded magnesite brick( also named as unfired magnesite brick).
Magnesia Brick Charcteristics
High refractoriness
Good alkaline slag resistance
Erosion resistance
Excellent anti-oxidation
High refractoriness under load
High mechanical strength
Volume stability at high temperature.
