The meaning of cermet is ceramic metal:
- By fusing GIC powder along with silver particles by sintering at high temperatures the product is known as cermet.
- Microfie silver alloy particles of 40% weight and less than 3.5 µm in diameter are mixed with glass powder particles and then sintered together at 800°C under pressure.
- Unreacted silver particles are washed out. Up to 5% of titanium dioxide is added to modify the color.
- The pellet that is formed is ground into fine particles which are cermet
