Abstract
The invention relates to an abrasion-resistant ceramic-based material, belonging to the field of ceramic materials. The abrasion-resistant ceramic-based material consists of a ceramic matrix and a glaze on the ceramic matrix, wherein the glaze is prepared by the following process: sintering, crushing and grinding aluminum oxide powder, titanium oxide powder, andalusite powder, silver oxide powder and silicon dioxide powder, mixing with an inorganic pigment, melting at 1100-1350 DEG C, and quenching the obtained melt; and crushing the obtained block, grinding till the average particle diameter is not more than 500nm, adding polyvinyl alcohol, and mixing uniformly. The glaze on the surface of the material has relatively high antibacterial performance and flame-retardant and fireproof performance.
