| 内容： | In a ceramic heater (3), a heater (32) is embedded in basal ceramic body which is prepared with silicon nitride as a main constituent. MoSi2 particles are dispersed in the basal ceramic body. In this instance, the granular diameter of the MoSi2 particles ranges from 0.1 to 3.0 mu m by observing a cross sectional texture of the ceramic heater (3). The heater (32) is prepared mainly by silicide, carbide or nitride of one or more metals selected from the group consisting of W, Ta, Nb, Ti, Zr, Hf, V, Mo and Cr. |
