Ceramic Insulators

Hot pressing sintering combines the use of heat with one or two phases of applied pressure. Microwave sintering applies microwave electromagnetic fields to sinter the ceramic material. Spark plasma sintering applies direct current pulses to the ceramic material, triggering fast fusing between particles.
