  "abstract": "Friable abrasive particles, particularly diamond particles, are produced by causing suitable material, such as a chloride salt, to be occluded in the particles during their manufacture and then removing some of this material, for example, by leaching.",
  "claims": [
    "1. A method of producing friable diamond particles including the steps of subjecting a reaction mass to temperature and pressure conditions suitable for producing the particles, the reaction mass comprising a source material for producing diamond, a metallic diamond solvent and sodium chloride capable of being occluded in the diamond particles so produced and being removed therefrom, recovering the diamond particles from the reaction mass, and removing at least some of the occluded material from the diamond particles. (according to claim 1 wherein the chloride salt is sodium chloride.)"
