Alumina ceramic tile adopt dry pressing technology forming and sintering by high temperature. It can be used as the internal protection layer of equipment and pipeline with various wear corrosion and high temperature. The alumina ceramic tile has good property in wear resistance, corrosion resistance, high temperature resistance, and the outer surface is smooth to facilitate the material through. Alumina ceramic tile is mainly use in fire power, mining, metallurgy, chemical and construction etc. It can effectively prolong the service life of equipment and pipeline.
