Method for producing solid ceramic particles using a spray drying process

Methods for producing solid, substantially round, spherical and sintered particles from a slurry of a calcined, uncalcined or partially calcined raw material having an alumina content of greater than about 40 weight percent. The slurry is processed with spray drying methods into solid, substantially...

Zusammenfassung:	Methods for producing solid, substantially round, spherical and sintered particles from a slurry of a calcined, uncalcined or partially calcined raw material having an alumina content of greater than about 40 weight percent. The slurry is processed with spray drying methods into solid, substantially round, spherical and sintered particles having an average particle size greater than about 200 microns, a bulk density of greater than about 1.40 g/cc, and an apparent specific gravity of greater than about 2.60.
