Abstract 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. В изобретении предлагается способ приготовления твердых спеченных керамических частиц, которые являются главным образом круглыми и сферическими, из суспензии, в которую входят кальцинированный, некальцинированный или частично кальцинированный исходный материал, имеющий содержание оксида алюминия ориентировочно свыше 40%. Суспензию подвергают обработке при помощи процессов распылительной сушки, чтобы получить твердые, главным образом круглые и сферические спеченные частицы, имеющие средний размер ориентировочно свыше 200 мкм, объемную плотность ориентировочно свыше 1,40 г/см и кажущуюся удельную массу ориентировочно свыше 2,60.
