Optical properties of translucent zirconia: A review of the literature
Translucent monolithic zirconia is the newest option of zirconia-based ceramics, which aimed to substitute the opaque classic yttria-stabilized tetragonal zirconia polycrystal (Y-TZPs) in more demanding esthetic cases.

Making yttria-stabilized tetragonal zirconia translucent [PDF]
The aim of this study was to provide a design guideline for developing tetragonal yttria-stabilized zirconia with improved translucency.The translucency, the in-line transmission in particular, of 3mol.% yttria-stabilized tetragonal zirconia (3Y-TZP) has been examined using the Rayleigh scattering model.

High Temperature Stability of Yttria Stabilized Zirconia
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。

Cytotoxicity and biocompatibility of high mol% yttria containing zirconia [PDF]
ObjectivesYttria-stabilized tetragonal phase zirconia has been used as a dental restorative material for over a decade. While it is still the strongest and toughest ceramic, its translucency remains as a significant drawback.
