Abstract
The present invention relates to a method for producing abrasive grains. According to the invention the method is characterised by the steps of manufacturing a polycrystalline body comprising diamond particles in a matrix of silicon carbide and silicon, or alternatively metal-silicon-carbon or boron-silicon-carbon phases, and crushing the polycrystalline body into grains. The invention also relates to abrasive grains produced by the method.
Claims22
A low pressure method for producing abrasive grains comprising the steps of forming a work piece from diamond particles, heating the work piece and controlling the heating temperature and heating time so that graphite is created by graphitization of diamond particles during the heat treatment of the work piece in an amount of 1-50 wt-% of the amount of diamond, thereby creating an intermediate body, infiltrating silicon or silicon alloy into the intermediate body, thereby creating a polycrystalline body, and thereafter crushing the polycrystalline body into grains.
