Abstract

PURPOSE:To obtain a ceramic material useful as a heater supporting material for glow plug, having excellent electrical insulating properties and variable coefficient of thermal expansion, by packing aggregated parts of a specific additive with a parent material such as Si3N4 and constituting a mutually separated sintered texture. CONSTITUTION:(a) A parent material is obtained from one or more materials selected from Si3N4, AlN and sialon. Then (b) an additive consisting of one or more materials selected from a carbide, silicide, nitride or boride of metal having a higher coefficient of thermal expansion than the parent material a is obtained. Then the component a is blended with the component b in the volume ratio of the component a and the component b of 5-25:95-75 and optionally >=3wt.% sintering auxiliary comprising alumina to give (c) mixed raw material powder. Then the component c is sintered by a hot press to form aggregated parts A having particles of the component b in an island state, to give a sintered texture wherein the aggregated parts are surrounded by the particles of the component a and a ceramic material having >=10<5>OMEGAcm specific resistance of sintered material is obtained.
