Magnesite zircon brick
Introduction:
Magnesite-zirconium bricks are made of high-purity fused magnesite and synthetic magnesite-zirconium sand. After high-pressure molding and high-temperature sintering, the main mineral phases are periclase, forsterite and oblique zircon. The material has excellent corrosion resistance to alkali metals, oxides and vulcanization.
Advantages:
Excellent corrosion resistance, good thermal shock resistance, excellent high temperature strength and thermal stability
Application:
It is used in the middle and upper part of the lattice of the glass kiln regenerator, and the service life time can reach more than 8 years without clogging and collapse.
