CERAMIC AND METHOD FOR PRODUCTION THEREOF |
摘要 |
A ceramic which comprises Mn, Ti, Fe, Si, Ca, Mg and 80 wt % or more of alumina (Al2O3) and also contains Mn-Al spinel (MnO.Al2O3) crystals and anorthite (CaO.Al2O3.2SiO2) crystals both having been formed by firing, and has a volume resistivity of 1 X 10<11>ohm.cm or less. It is preferred that the ceramic contains Mn, Ti and Fe in a total amount of 2 to 11 wt % in terms of oxides, and contains Mn in an amount of 0.5 wt % or more in terms of an oxide (MnO), Ti in an amount of 0.5 wt % or more in terms of an oxide (TiO2) and Fe in an amount of 0.5 wt % or more in terms of an oxide (Fe2O3).
