Advanced ceramics work at temperatures way above standard ceramics that are clay based , theseare typically in the region of 650c, and advanced ceramics are considered up to 2200c and thenspecialist ceramics classed as UTC or ultra high temperature ceramics operate above thattemperature band but these are rare materials. When compared to stainless steel this melts between1400-1500c, so advanced ceramics can provide a useful solution in critical applications such as aeroengines and semiconductor heaters.When considering materials to be used around 2000c attention should be paid to the atmosphere asmost of these materials are nitride or carbide based , and need an inert atmosphere to work as thepresence of oxygen can limit the temperature at which these function.At higher temperatures, its worth discussing other operating conditions such as thermal shockelectrical performance to understand the requirement fully, Materials such as silicon Carbidefunction well at 2000c and work well with thermal shock, but are not electrical insulators, andalternate materials such as Boron Nitride or Shapal may need to be considered.
