The basic refractories with magnesium oxide content of over 92% and magnesite as the main raw material are called magnesia refractory bricks. It can be divided into sintered magnesia brick and chemical magnesia brick. High purity magnesia brick is directly contacted by magnesite, so it is also called direct contact magnesite brick. There are electrofused … Read more
