Magnesia zircon brick description
Magnesium-zircon bricks are made of high-purity fused magnesia and synthetic magnesium-zircon sand. After high-pressure molding and high-temperature sintering, the main mineral phases are periclase, forsterite and oblique zircon, and alkali metal , oxides and sulfides have excellent corrosion resistance. It is used in the middle and upper part of the lattice of the glass kiln regenerator, without clogging and collapse, and the service life can reach more than 8 years. Its high temperature strength and thermal stability are better than re-combined magnesia bricks, and it has a good use prospect in the glass kiln regenerator.
