Method of producing ultra-hard abrasive particles |
摘要 |
A method of producing a plurality of discrete ultra-hard abrasive particles includes the steps of providing a plurality of granules, each comprising at least one ultra-hard abrasive particle, a precursor for the abrasive particle and a solvent/catalyst for the abrasive particle or precursor of such a solvent/catalyst, placing the granules with a separating medium between adjacent granules in the reaction zone of a high pressure/high temperature apparatus, subjecting the contents of the reaction zone to elevated temperature and pressure conditions at which the ultra-hard abrasive particle is crystallographically stable, recovering thus treated material from the reaction zone and removing the separating medium in the treated material to produce a plurality of discrete abrasive particles.
