Procedure

U.S. Pat. No. 2,739,073 issued on Mar. 20, 1956 to Bertorelli and was assigned to the J. M. Huber Corporation. In this patent, a dilute sodium silicate solution and a dilute aluminum salt are added slowly to a diluting aqueous medium to produce a precipitated sodium alumino silicate having a specific gravity of from 2.10 to 2.26 and substantially all of the particles are less than 0.5 microns in diameter.
