ZIRCONIA SINTERED BODY, AND MIXTURE, PRE-SINTERED COMPACT AND PRE-SINTERED CALCINED BODY FOR SINTERING ZIRCONIA SINTERED BODY |
摘要 |
Provided is a high-strength zirconia sintered body in which the progression of low-temperature degradation is inhibited. The zirconia sintered body contains partially-stabilized zirconia as a matrix phase and contains at least one element from among phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi). The content of the abovementioned element(s) in the zirconia sintered body ranges from 4×10 -4 mol to 4×10 -2 mol with respect to 1 mol of zirconium(IV) oxide. Preferably, the zirconia sintered body further contains 0.03% to 3% by mass of silicon dioxide. |
