METHOD FOR PRODUCING SOLID CERAMIC PARTICULARS USING A SPRAY DRYING PROCESS refers to methods for producing substantially circular, spherical and sintered solid particles from a slurry of a calcined, non-calcined or partially calcined raw material. has an alumina content of greater than about 40 weight percent. The slurry is processed by spray drying methods to form substantially circular, spherical and sintered solid particles having an average particle size greater than about 200 microns, a mass density greater than about 1.40 g / cm ¬ 3¬, and an apparent specific weight greater than about 2.60. |
