Abstract
A material containing corundum crystals from 5 to 350 microns in size and any one of the additions: spinel, anorthitic glass, cordieritic glass, or a mixture of spinel and either of said glasses. Said addition amounts to 1.5-7.5% by mass of the abrasive material and is spread between the corundum crystals in the form of interlayers less than 20 microns thick.
