Cerium Oxide Powder for Precision Optics Polishing (640 kg pack)
Description
The BKA-1520 Cerium Oxide Polishing Powder is a high-performance rare-earth abrasive designed for ultra-precise polishing of optical components. Engineered with a controlled particle size distribution, it offers superior surface finish and fast material removal rates for demanding applications. With a D50 particle size range of 1.8 – 2.4 µm and D90 ≤ 6 µm, BKA-1520 is particularly suited for fine polishing of optical filters, glass molds, hard nitrate materials, and ophthalmic lenses. The powder is composed predominantly of cerium oxide (60–80%) with a significant portion of lanthanum oxide (20–40%), ensuring optimal hardness and polishing efficiency. Its white color, consistent quality, and optimal pH (6–8) make it an ideal choice for applications requiring clarity and scratch-free finishes, such as precision polishing and ophthalmic lens manufacturing.
Note: The performance of the BKA-1520 is similar to Cerox 1663.
Minimum order quantity of this powder is 640 kg.
