Technical Ceramics from The Ceramic Experts

Technical ceramics from CeramTec can be divided into four major groups of ceramic materials: Silie ceramics, oxide ceramics, non-oxide ceramics and piezo-ceramics. Silie ceramics are the oldest type of ceramic materials for technical appliions and are made primarily from natural raw materials in conjunction with alumina (aluminum oxide, aluminum silie).

Hot Surface Igniter Operation and Troublehooting

2001/3/1· Some service technicians may be surprised to learn that the silicon carbide element of a hot surface igniter (HSI) can be handled without damage. However, it is better and safer to handle the igniter by the ceramic holder. The myth that the silicon carbide tip cannot

Thermal insulators - CarboSystem

One of the best thermal insulators is the void, where the heat can only be transmitted by radiation, but as the void is very hard to obtain and maintain, it is not used regularly. In real life situations, it is used air with a very low humidity, avoiding conduction and radiation heat transference, thanks to the low absorption coefficient.
