Cerium Oxide Polishing Powder

{Welcome to inquire by letter}>>>Contact HonWay

Cerium oxide polishing powder has excellent chemical and physical properties, so it has been widely used in the polishing of industrial products, and has been used in the polishing of various optical glasses, LCD TVs, optical spectacle lenses, oscilloscopes, mobile phones, tablet PC related products, semiconductor chips and metal precision products. The larger the particle size, the greater the grinding force, and the more suitable it is for harder materials; Glass applications, on the other hand, tend to use finer polishing powders. It is important to note that there is a distribution problem in the particle size of all cerium oxides, the average particle size or the median size (D50) can determine the polishing speed, and the maximum particle size (Dmax) determines the polishing accuracy. Therefore, in order to obtain the requirements of high precision, it is necessary to control the maximum particle size of the polishing powder.
