ABSTRACT:
An aqueous suspension of porous glass particles having a closely controlled average particle size within the range of about 0.7 to about 3.0 microns. The controlled particle size porous glass particles are prepared by initially milling course porous glass particles to yield particles of about 10 microns or less, leaching those particles to remove contaminants and residues, rinsing the particles, and then mixing the particles with an aqueous solution and subjecting the mixture to at least two controlled sedimentation steps.
