Praseodymium Cerium Oxide Polishing Powder
DESCRIPTION:
Praseodymium Cerium Oxide Polishing Powder has a higher grinding removal rate and better polishing smoothness than pure cerium oxide. The higher the praseodymium oxide content, the more vibrant the color of the cerium oxide powder. Praseodymium-cerium polishing powder is widely used for polishing and surface treatment of optical glass, optical lenses, LCD glass, mobile phone cover plates, sapphire filters, LCDs, semiconductor wafers, as well as flat glass, crystal, and prisms.
Features:
- High Cutting Force. Due to the synergistic effect of cerium oxide and praseodymium, the polishing powder exhibits high cutting force, significantly shortening polishing time.
- Long Service Life. The polishing powder is not easily worn during use, maintaining polishing effects for a longer period.
- Good Polishing Precision. The uniform and fine particle size of the polishing powder ensures a high surface finish after polishing, meeting the requirements of high-precision polishing.
- The praseodymium content affects the color of the polishing powder. Generally, polishing powder with a higher praseodymium content will appear brownish-red.
