Sintering
In the firing process, raw materials that are compression-molded (volumetric filling rate: approx. 60%) are heated at temperatures below their melting points to sinter powder and create density. Ceramic powder particles induce mass transfer at high temperatures through contact points between particles, combining in a manner similar to water droplets. Depending on the intended application, a variety of sintering methods may be used — such as vacuum sintering, atmosphere sintering and sintering in non-oxidizing atmospheres.
