Disclosed herein are stabilized kaolin slurries comprising a kaolin comprising no more than about 80% by weight of particles having an equivalent spherical diameter of less than 2 microns and at least one stabilizer, wherein the stabilized kaolin slurry has a 28-day pour test result of at least about 80% poured. Also disclosed are methods of making such stabilized kaolin slurries.
1. A method of making a stabilized kaolin slurry, comprising: filtering and rinsing a kaolin slurry to remove salt residue therefrom until said resulting kaolin has a conductivity of no more than about 100 μS; resolubilizing said resulting kaolin to form a resolubilized slurry; and adding at least one stabilizer to the resolubilized slurry, wherein said stabilized kaolin slurry comprises kaolin having a shape factor of at least 25. 2. The method according to claim 1, wherein said stabilized kaolin slurry has a 28-day pour test result of at least 80% pour...
