Degradation kinetics of high-translucency dental zirconias: Mechanical properties and in-depth analysis of phase transformation
(2020-02-01)
This study aimed to evaluate the effects of low temperature degradation (LTD) on commercial dental zirconias (conventional and high-translucent - HT) with different microstructures, as well as on their mechanical properties ...
Bond strength of zirconia to different core materials
(2016-10-01)
Background: Since bonding to zirconia is still questionable,the aim of this study was to evaluate the bond strength of yttrium-stabilized tetragonal zirconia polycrystal (Y-TZP) to different materials used to manufacture ...
Application of Micro-Raman Spectroscopy to the Study of Yttria-Stabilized Tetragonal Zirconia Polycrystal (Y-TZP) Phase Transformation
(Soc Applied Spectroscopy, 2015-07-01)
The aim of this study was to perform micro-Raman spectroscopy as an alternative and nondestructive method to identify the phase transformation of zirconia after mechanical stress. The groups evaluated were experimental ...
Efeito de técnicas de pigmentação pré- e/ou pós-sinterização no comportamento mecânico de uma zircônia translúcida para restaurações monolíticas
(Universidade Federal de Santa MariaBrasilOdontologiaUFSMPrograma de Pós-Graduação em Ciências OdontológicasCentro de Ciências da Saúde, 2022-08-17)
The present dissertation aimed to characterize the effect of pre- (shading) and/or post- (staining) sintering pigmentation techniques to provide a Vita Classical A2 color on the mechanical properties of a 4YSZ ceramic (IPS ...
Estudo da zircônia reforçado com alumina
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia de MateriaisProcessamento de Materiais a partir do Pó; Polímeros e Compósitos; Processamento de Materiais a part, 2008-12-29)
Ceramics materials have good properties including chemical stability, high hardness and wear resistance. Moreover, due to its fragility, can suffer failure under relatively low levels of tension. Actually zirconia is the ...
On the stabilizing behavior of zirconia: A combined experimental and theoretical study
(Kluwer Academic Publ, 2004-03-15)
Reactive zirconia powder was synthesized by the complexation of zirconium metal from zirconium hydroxide using a solution of 8-hydroxiquinoline. The kinetics of zirconia crystallization was followed by X-ray diffraction, ...
