The influence factors of abrasion resistant tile
To obtain high wear resistance of Al2O3 ceramic material, not only should consider to make it with high density, flexural and compressive strength, and to improve its hardness and fracture toughness, and these properties and the microstructure of Al2O3 ceramics (closed porosity, grain size and distribution of glass phase, etc.) and its wear mechanism are closely related. Alumina ceramic preparation of various process conditions are sintering and the microstructure of it has great influence.They include: the preparation process of powder, particle size and particle size distribution, forming method, green density, sintering temperature, heating rate, holding time, sintering atmosphere, whether pressure and so on.Core property of abrasion resistant tile of pottery and porcelain is to control the three main factors: the best alumina materials and the preparation method of grinding grading, high density, reasonable sintering temperature and holding time, the produc...
