Abstract

An abrasive composition, which is particularly suitable when used as a 10% liquid suspension for polishing glass or stone, comprises (a) finely divided zircon (ZrSiO4), preferably in an amount of 10-90% by weight of the composition, and (b) at least one finely divided oxide selected from zinc oxide, ferric oxide and cadmium oxide. A favoured composition consists of 40% (by weight) zircon, 50% zinc oxide and 10% ferric oxide. In general the particle size of the constituents should be less than 3m average, and preferably less than 2 m , and if required zirconia (ZrO2) may also be included in the composition. The suspension to be used may contain deflocculants and thickeners.
