MATERIAL "NEOPOL" FOR MANUFACTURING HARD POLISHING INSTRUMENT Russian patent published in 1996 - IPC

FIELD: production of polishing materials. SUBSTANCE: solid polishing material "Neopol" useful in suspensionlessly polishing parts made of optical glasses and various-type sitals is based on low-cost inorganic binder. Novelty consists in that material contains abrasive and ceramic binder composed, wt. - %: boron oxide 1.2-10.0, silica 0.5-6.0, alumina 0.6-1.0, potassium carbonate 0.07-1.30, magnesium trioxide 0.08-1.30, calcium oxide 0.04-0.20, sodium carbonate 0.05-0.20. Ratio of abrasive (cerite) to binder is (80-98):(2-20). EFFECT: enhanced performance. 2 cl, 2 tbl
