Abstract: A method of forming a colloidal dispersion includes providing a first continuous material flow, providing a second continuous material flow, combining the first and second continuous material flows, and moving a continuous flow of a colloidal dispersion in a direction downstream of the first and second continuous flows. The first continuous material flow includes one or more of a diluent (e.g., deionized water), a base, and an acid, and the second continuous material flow includes an abrasive particle solution. The first and second material flows are combined with a Reynolds number greater than about 4400 and less than about 25000 (e.g., about 74000 to about 25000). The colloidal dispersion includes the diluent, the base, the acid, and abrasive particles from the abrasive particle solution.
