Abstract:
Ceramic sintering apparatus comprising:(a) a feed of particulate granular green oxide particles;(b) an elongate tube having an open upper inlet end and a lower open outlet end and a heating zone between the ends to receive a flow of particles moving through the tube in a controlled time interval in the heating zone, wherein said tube is attached within a cylindrical housing to a support therein, and said tube is positioned at an inclined angle with respect to the major axis of said cylindrical housing;(c) a drive moving said tube so that particles move toward the outlet end thereof;(d) a microwave generator operatively connected to direct microwave energy into said zone to heat the particles for a desired time and temperature to sinter the particles; and(e) said support for said tube controls said angle of inclination so that said green oxide particles are moved along the tube for the desired time controlled by the inclination of the tube.
