Abstract:
A method of coating particles, comprising the steps of:placing said particles in a container comprising at least one side wall, a cathode forming an electrically conductive inner surface of said side wall of said container;filling said container with an electrically conductive fluid so as to immerse said cathode together with an anode; andcreating a fluidized bed of said particles by causing said container to rotate so as to generate a centrifugal force while simultaneously agitating said particles, and while causing electrical current to pass through said container, said centrifugal force and said agitating causing said particles to remain immersed in the electrically conductive fluid and remain in electrical contact with said electrically conductive inner surface of said side wall of said container while said electrical current passes from said cathode to said anode, so as to result in substantially uniform deposition of a coating material from said electrically conductive fluid onto said particles.
