Magnesite zircon brick is also known as Magnesia zirconia brick. It is a type of basic refractory brick. It most frequently operates in the most challenging conditions of upper-middle zone in glass melting furnace regenerator.

Magnesite zricon brick introduction
Magnesite zircon brick is made of high purity fused magnesia sand and high quality synthetic magnesia zirconium sand. It is formed by pressure molding and fired at high temperature. In its microstructure, the main crystal phases are magnesia galerite, magnesium peridotite and zircon slanting.
Magnesite zricon brick characters
Magnesite zircon brick has excellent corrosion resistance to alkali metals, oxides and sulfides etc., and at the same time, this product has a high volume density and its softening temperature under load is extremely high.
Magnesite zricon brick application
Magnesite zircon brick is mainly working as upper and middle checker brick in regenerator of glass kiln, with long service life without clogging and collapse. In addition, magnesite zircon brick is also widely used in cement kiln, steelmaking electric arc furnace and non-ferrous metal smelting.
