  • Method of Sintering Ceramic Materials
    Publication number: 20100230871
    Abstract: A method of sintering a ceramic material comprises increasing the temperature of the ceramic material to a first predetermined temperature and maintaining the temperature of the ceramic material at the first predetermined temperature for a predetermined time period to increase the grain size of the ceramic material. Increasing the temperature of the ceramic material to a second predetermined temperature, decreasing the temperature of the ceramic material to a third predetermined temperature to freeze the grain size of the ceramic material and maintaining the temperature of the ceramic material at the third predetermined temperature for a third predetermined time period to densify the ceramic material. Finally decreasing the temperature of the ceramic material to ambient temperature. The method increases the density of the ceramic material. Used for electrolyte layers of solid oxide fuel cells.
