What’s the Factors Affecting the Alumina Ceramic tiles quality
1. The influence of raw material powder The most important raw material for alumina wear resistant ceramics is high-purity alumina powder. Its performance and content have a great influence on alumina wear-resistant ceramics. The ceramic powder will inevitably introduce impurities during the preparation process, and the organic impurities will be burned during the sintering process, forming irregular pores during the densification process; the inorganic impurities will react with the ceramic powder at high temperature or in the matrix Formation of microcracks. These impurities have a significant effect on the densification of alumina ceramics. The particle size of the raw material powder also has a great influence on the performance of the product. Only when the raw material is fine enough, the final sintered product can form a microcrystalline structure, which makes it have good wear resistance. Therefore, high-purity, fine-grained alumina powders are an important prerequisite ...
