摘要：

This disclosure relates to a process for preparing a treated inorganic core particle having improved dispersability comprising: (a) heating a slurry comprising porous silica treated inorganic core particle and water at a temperature of at least about 90° C.; and (b) adding a soluble alumina source to the slurry from step (a) while maintaining the pH at about 8.0 to 9.5 to form an alumina treatment on the porous silica treated inorganic core particle; wherein the treated inorganic core particle does not comprise dense silica or alumina treatments, and has silica present in the amount of at least about 7% up to about 14% and alumina present in the amount of about 4.0% to about 8.0%; and wherein the particle to particle surface treatments are substantially homogeneous.
