High Purity Alumina For Sapphire Polishing
High purity alumina powder has an excellent removal rate that is more than four times higher than silica, combined with fast polishing and excellent surface finish of less than 3 angstroms Ra.
Product Introduction
Product introduction
Compared with soft abrasives such as SiO2, high-purity alumina polishing powder has obvious advantages in removal rate when processing sapphire. Because the size, shape and particle size distribution of alumina particles will affect the polishing effect.
Sapphire polishing is mainly used in the polishing of sapphire substrates, windows, optical glass and other non-metallic materials.
High purity alumina polishing powder has the advantages of good stability and dispersibility, high removal rate, good surface effect and no damage to the workpiece. Even in the case of high dilution ratio, it still has good polishing efficiency and service life.
Moreover, high purity alumina polishing powder has good particle size dispersion, which effectively avoids scratches on the surface of the workpiece caused by particle agglomeration; the chemical action is mild, and it will not produce pitting, orange peel, pinholes and other defects.
Product advantages
High purity alumina polishing powder produced by Avant has the characteristics of good powder dispersion, high primary crystal strength, small primary crystal size, high removal rate, small specific surface area and so on. It can be well diluted and proportionally mixed with various auxiliaries to make more polishing fluid.
Avant is a manufacturer in Zibo, Shandong that uses its own aluminum hydroxide as raw material, and has been focusing on alumina materials for 13 years.
We have been committed to the continuous innovation, research and improvement of powder materials. It has brought higher quality products and value returns to customers at home and abroad.
