  • Crystallization of powders having uniform particle sizes by Ostwald ripening at large levels of supersaturation
    Patent number: 6379459
    Abstract: A method is provided for the manufacture of mineral power crystals having a uniform mean size. The method includes forming a solution which is highly supersaturated with respect to the crystals. The crystals of the solution are Ostwald ripened at a level of supersaturation that produces an Ostwald steady state crystal size distribution shape wherein the crystals are of a uniform size. After Ostwald ripening ceases, the crystals further grow by supply controlled growth which uniformly increases the size thereof. This enables the supply controlled growth to be terminated at a selected, controlled point so as to produce a desired mean crystal size.
