Method of abrading with boron suboxide (BxO) and the boron suboxide (BxO) articles and composition used

摘要

The invention refers to an abrasive tool, a lapping and polishing powder and lapping slurry made from a dense, finely crystalline boron suboxide material with a Knoop hardness KHN100 of at least about 2800 kg/mm2 and preferably at least 3800 kg/mm2. Further provide is a method of removing material from a surface comprising the step of abrading a surface with an abrasive tool, an abrasive powder or slurry comprising a boron suboxide (BxO) composition, wherein during the abrading step the boron suboxide (BxO) composition is maintained at low temperatures. The abrasive which is from the boron suboxide (BxO) family of compounds exhibits an unexpectedly high quality of abrading comparable with the highest quality particulate natural and synthetic diamond, which has a hardness about double that of the boron suboxide (BxO) of the present invention.
