Electrically conductive zirconia-based sintered body and process for the production thereof.

摘要

A zirconia-based sintered body comprises 50 to 10 vol.% of TiN and 50 to 90 vol.% of TiO2 + ZrO2 wherein either (a) the amount of TiO2 is more than 10% by weight based on TiN and the amount of Ti of TiO2 is in the range of 1.5 < Ti </= 10 in percentage by weight or (b) the amount of Ti of TiO2 is in the range of 0.3 < Ti </= 10 in percentage by weight and 10 to 40% of crystalline phase of ZrO2 in the sintered body is monoclinic. Processes for the production thereof are also described.
