Assignee:
Saint Gobain/Norton Industrial Ceramics Corporation - Worcester MA
International Classification:
B02C 1900, B02C 1912
US Classification:
241 1
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.
