Magnesia fireclay is made from synthesizing, adopting high quality fireproof powdery materials and compound binder operation assistant agents etc.
It has the characteristics of high intensity,good fluidity, small contraction,strong resistance to corrosion,thin joint layer and convenient field operations etc.
It is the ideal match-material for placing jointing and coating of firebrick of various industrial furnaces.
