CONDUCTIVE CERAMIC MATERIAL AND PRODUCTION METHOD THEREOF

摘要

12CaO.7Al2O3 polycrystal having high conductivity is provided. It has become obvious that the conductivity of the 12CaO.7Al2O3 polycrystal becomes 100 [S/cm] or more by controlling a nitrogen content in the 12CaO.7Al2O3 polycrystal within a range of 0.3 to 1.1 [wt %], and that the conductivity becomes 150 [S/cm] or more by controlling the nitrogen content within a range of 0.5 to 0.9 [wt %].
