Black zirconia composite sintered body and method for producing same
Provided is a black zirconia composite sintered body having excellent machinability in a sintered body state. The present invention pertains to a black zirconia composite sintered body containing ZrO2, HfO2, a stabilizer capable of suppressing phase change of zirconia, and Nb2O5 and/or Ta2O5, the total content of ZrO2 and HfO2 being 78-97.5 mol%, the content of the stabilizer being 1-12 mol%, the total content of Nb2O5 and Ta2O5 being 1-9 mol%, and the total content of Nb2O5 and Ta2O5 being 1-9 mol% per 100 mol% of the total of ZrO2, HfO2, stabilizer, Nb2O5 and Ta2O5. The black zirconia composite sintered body further contains an element or ion derived from an end-capping reagent.
本发明提供在烧结体的状态下机械加工性优异且呈黑色的氧化锆复合烧结体。本发明涉及黑色氧化锆复合烧结体，其包含ZrO2、HfO2、能够抑制氧化锆的相变的稳定剂、和Nb2O5及/或Ta2O5，在ZrO2、HfO2、前述稳定剂、Nb2O5及Ta2O5的合计100摩尔％中，ZrO2及HfO2的合计含有率为78～97.5摩尔％，前述稳定剂的含有率为1～12摩尔％，Nb2O5及Ta2O5的合计含有率为1～9摩尔％，所述黑色氧化锆复合烧结体还包含源于封端剂的元素或离子。
