Abstract: Una alumina sol-gel que es secada pero no horneada puede triturarse explosivamente introduciendo el gel secado a un horno mantenido a temperaturas superiores a aquellas a las cuales se eliminan los materiales vaporizables de las partículas de gel; a temperaturas adecuadamente elevadas el horneado es suficiente para formar partículas densificadas de alfa-alumina de un tamaño adecuado para su uso directo como granos abrasivos.

Abstract: Sol-gel alumina that is dried but unfired can be explosively comminuted by feeding the dried gel into a furnace held at temperatures above those at which vaporizable materials are eliminated from the particles of gel. At suitably elevated temperatures the firing is sufficient to form fully densified alpha alumina particles of a size suitable for direct use as abrasive grits.
