Claim:
1. A method of forming a colloidal dispersion, the method comprising: providing a first continuous material flow comprising a diluent, a base, and an acid; providing a second continuous material flow comprising an abrasive particle composition; and combining the first and second continuous material flows with a Reynolds number greater than about 4400 and less than about 25000 to form a colloidal dispersion; and moving a continuous flow of the colloidal dispersion in a direction downstream of the combined first and second continuous material flows, wherein the abrasive particle composition has a pH above or below the isoelectric potential of the colloidal dispersion, wherein combining the first and second material flows comprises moving the first and second continuous material flows through at least one static mixer and said combining increases or decreases the pH through the isoelectric potential of the colloidal dispersion, and wherein the colloidal dispersion comprises the diluent, the base, the acid, and abrasive particles from the abrasive particle composition and the colloidal dispersion is substantially free of a microgel.
