  • Dynamic control and enhanced chemical milling of ceramics to submicron particle sizes
    Patent number: 6415996
    Abstract: Chemically aided milling of ceramic powders is disclosed. Carrier suspension, usually aqueous, of the ceramic powder may have added to it a dispersing agent and a passivating agent, followed by milling the aqueous suspension while continuously monitoring the pH, and as necessary, adding acid or a base to keep the pH within a desired range during milling. Real time monitoring allows milling with lower energy consumption, and enhances the desirable particle surfaces of the ceramic powder. The passivating agent can also be real time monitored and adjusted as necessary.
