Brief Introduction
Magnesia zirconia brick has the characteristics of compact structure, small porosity and uniform distribution, high strength under high temperature, good thermal shock resistance, good resistance to alkaline atmosphere and alkaline slag corrosion, and excellent kiln coating hanging performance.
It is suitable for firing zone of cement kilns and regenerator of glass kilns.
