HOW TO CHOOSE ALUMINA POLISHING POWDER
When it comes to the precision machining of various materials, cutting, grinding and polishing process plays a key role. Talking about the polishing process, polishing powder is a key factor. The most common polishing powder includes alumina polishing powder and cerium oxide polishing powder, between them alumina solution polishing powder is especially widely used. According to different crystal phases, aluminium oxide polishing powder includes α-alumina powder, β-alumina powder and γ-alumina powder. The physical and chemical properties of aluminum oxide powders with different crystal phases are different. Among them, the crystal structure of α- alumina powder is relatively stable, with high melting point, high hardness, high heat resistance and good insulation properties. So it is widely used in electronic materials filler, artificial medical materials, catalysts and so on.
