MANUFACTURING METHOD OF CONDUCTIVE CARBONIZED SILICON SINTERED BODY AND CONDUCTIVE CARBONIZED SILICON SINTERED BODY
To provide a manufacturing method of a sintered body that is an electric conductive carbonized silicon sintered body containing nitrogen as a dopant and exhibits smaller specific resistance value, that is, exhibits higher electric conductivity.SOLUTION: A manufacturing method of conductive carbonized silicon sintered body comprises: a molded body firing process of firing a molded body formed from a raw material containing aggregate grains to obtain a sintered body having a conductive phase that is a carbonized silicon phase containing nitrogen as a dopant; and a reaction and firing process of firing a silicon source and a carbon source in a non-oxidation atmosphere containing nitrogen gas to react and produce carbonized silicon containing nitrogen as a dopant. In the manufacturing method of conductive carbonized silicon sintered body, the sintered body with different specific resistance value is manufactured by obtaining the aggregate grains through the reaction and firing process, and increasing nitrogen concentration of the aggregate grains by raising the temperature of the reaction firing process.SELECTED DRAWING: Figure 1
