Divided into calcined alumina and ordinary industrial alumina, calcined alumina is essential raw material in the production of archaize brick, and industrial alumina can be used in the production of microcrystalline, in traditional glaze, alumina commonly used for whitening.Alumina ceramic abrasion resistant tile and microcrystalline in recent years the market favor, the amount of alumina is also increased year by year.According to market survey: as an important raw material of alumina ceramic brick production, even in the market situation of ceramic industry is generally low, many ceramic chemical raw materials prices by uncertain, but the price of alumina is always keep in a stable range, rarely affected by ceramic industry downturn, the role of visible in the alumina ceramics is indispensable.

Therefore, alumina abrasion resistant tile of pottery and porcelain in the ceramic industry has come into being - alumina ceramics is a kind of Al ? O ? as the main raw material, ceramic material is given priority to with corundum crystal phase. Because of its high mechanical strength, high hardness, low dielectric loss at high frequency, high temperature and high insulation resistance, chemical corrosion resistance and good thermal conductivity and other excellent comprehensive technical performance advantages.
