Zircon brick is a kind of refractory material, with zircon as the main component, with high refractory temperature and good chemical stability. Zircon is a tetragonal system, short columnar, with metal or glass luster, generally brown, light gray or red. In addition, zircon is insoluble in acid and alkali, non-magnetic or weak magnetic, weak conductivity.

Zircon bricks are widely used in the field of refractory materials, and can be used to make zircon bricks for glass kilns, zircon bricks for steel barrels, ramming materials and castables. Due to its excellent thermal shock resistance and acid resistance, zircon bricks are also widely used in the fields of ceramics, enamel and metal smelting.

The preparation method of zircon brick includes mineral processing, preparation of raw materials, molding, firing and other processes. In the beneficiation process, it is necessary to use heavy, magnetic, floating, electric and other methods to separate zircon from other minerals. The compressive strength and compressive strength of zircon brick are high, which can reach more than 300MPa, and has good fire temperature and thermal shock stability.
