الإجراء التجريبي

284 parts water were added to 244 parts of liquid Alum and cooled to 15° C. liquid sodium aluminate (24% al2O3) 135 parts diluted with 143 parts water was then added over one half hour to a pH of 6.1, the gel was mixed for one half hour under high shear. Alum liquid 456 parts, was then added and the temperature slowly raised over 11/2 hour to 58° C. and held at 58° C. for an additional 11/2 hour. Upon clearing the product was cooled and contained Al2O3 7.0% (partial increase due to evaporation loss) and a basicity of 51.5%.
