The materials are offered in two ultrapure grades and feature seven particle sizes from 0.05 to 3 μm for application directly to optics on mounted on spot blocks. Capable of producing finishes to 10-5 scratch-dig, they have large agglomerated particles for aggressive grinding and lapping that break down under pressure for final polishing and are 99.98% pure. Suitable for grinding, lapping, and polishing hard and soft materials including zinc selenide, germanium, silicon, and stainless steels, the petroleum-free abrasives can be mixed by the user with de-ionized water to achieve any ratio.More products
