ABSTRACT:
A ceramic heater having a heating element of a sintered mixture comprising alumina, titanium nitride and titanium carbide, is discribed. The heating element has a good oxidation resistance, and a relatively high temperature coefficient of resistance. The larger composition of titanium nitride acts to increase the temperature coefficient of resistance. The larger composition of alumina acts to prevent oxidation increase and to improve the sintering. The adequate composition of each ingredients can result in a suitable heating element for a ceramic heater.
