High Temperature Stability of Yttria Stabilized Zirconia
Netsu Bussei, 2007 イットリア安定化ジルコニアは熱物性に関する標準物質候補材料として研究が進められている。本研究では、ファインセラミックス共通試料であるリファセラムZR1（ジルコニア）を用い、標準物質材料として使用する際に重要となる高温安定性の評価を行った。高温安定性は、200～ 1500℃の温度で熱処理を行ったときの、熱処理前後の熱拡散率の変化より評価した。900℃以下の熱処理では熱拡散率に変化がほとんど見られなかったが、1000℃以上で熱処理すると、結晶相の変化や相分離および粒界に発生した亀裂などによって熱拡散率に変化が生じることが明らかになった。これらの結果より、リファセラムZR1 は900℃以下であれば安定であり、標準物質として適用できると判断された。

Enhanced reliability of yttria-stabilized zirconia for dental applications [PDF]
Acta Biomaterialia, 2015 An increasing number of dental applications based on yttria-stabilized zirconia (3 Y-TZP) have been developed in recent years as a result of the advances and versatility of dry-processing and soft machining at the pre-sintered state. Nonetheless, the long-term surface stability of these materials in humid environment is still a matter of concern and ...
