Maximum Temperature

Advanced ceramics work at temperatures way above standard ceramics that are clay based , these are typically in the region of 650C, and advanced ceramics are considered up to 2200c and then specialist ceramics classed as UTC or ultra high temperature ceramics operate above that temperature band but these are rare materials. When compared to stainless steel this melts between 1400-1500c, so advanced ceramics can provide a useful solution in critical applications such as aero engines and semiconductor heaters.

When considering materials to be used around 2000c attention should be paid to the atmosphere as most of these materials are nitride or carbide based , and need an inert atmosphere to work as the presence of oxygen can limit the temperature at which these function.

At higher temperatures, its worth discussing other operating conditions such as thermal shock , electrical performance to understand the requirement fully. Materials such as silicon Carbide function well at 2000c and work well with thermal shock, but are not electrical insulators, and alternate materials such as Boron Nitride or Shapal may need to be considered.
