ABSTRACT:
A layered lattice silicate in particulate form, such as kaolin, which contains naturally occurring organic material useful as a source of carbon or which contains an external source of carbon, is treated at elevated temperature in a hydrogen atmosphere to cause formation of silicon carbide at the surfaces of the particles. The product is an abrasive, useful in industrial products such as abrasive cleaners and sandpaper coatings, or as a filler for ceramics, elastomers and plastics.
