ABSTRACT:
A method is provided for drawing ions out of the glassy phase of a ceramic in order to improve its high temperature strength and to reduce its dielectric loss. The ceramic is heated to a high temperature to increase the mobility of the ions within the glassy phase. An electric field is then applied across the ceramic to draw the ions to the surfaces of the ceramic where they can be removed by grinding.
