Influence of surface topography and surface physicochemistry on wettability of zirconia (tetragonal zirconia polycrystal).
Surface modification technologies are available for tetragonal zirconia polycrystal (TZP) to enhance its bioactivity and osseointegration capability. The surface wettability of an implant material is one of the important factors in the process of osseointegration, possibly regulating protein adsorption, and subsequent cell behavior. The aim of this study was to clarify the effect of topographic...
متن کاملDetection of tetragonal zirconia in alumina–zirconia powders by thermoluminescence
The thermoluminescence (TL) after excitation by UV or X-rays radiation of alumina-zirconia powders is investigated. The composites present five of the characteristic peaks of zirconia at −170, −145, −90, 0 and 95 °C. After a thermal treatment of mixed oxides, a new peak is observed at −35 °C in TL. This peak reveals the presence of stabilized tetragonal zirconia in the material. Moreover by com...
متن کاملIncreasing of tetragonal zirconia formation in the reaction sintering of alumina-zircon
In this study it was tried to investigate on the effective parameters of the formation and increasing tetragonal zirconia phase in reaction sintering of alumina and zircon. In this way, alumina and zircon powders were mixed by the ratio of 85 to 15 wt.% and sintered at different conditions. Sintering temperature (1500-1650˚C), furnace type (conventional and microwave) and the milling time of r...
متن کاملWear performance of bovine tooth enamel against translucent tetragonal zirconia polycrystals after different surface treatments.
The wear performances of bovine tooth enamel (BTE) against translucent tetragonal zirconia polycrystals (TZP) compared to that of feldspar porcelain and the influence of surface treatments of translucent TZP were investigated by the two-body wear test. Translucent TZP and feldspar porcelain were used as hemisphere abrader specimens with a radius of curvature of 5 mm; flat BTE surfaces were used...
متن کاملLattice and grain boundary diffusion of cations in tetragonal zirconia
Zirconia is a widely used oxide ceramic in various high performance applications due to its attractive mechanical, electrical and thermal properties. In particular, the material 3 mol% yttria stabilized tetragonal zirconia (3YTZ) has been shown to undergo superplastic deformation [1]. One crucial step in the understanding of processes like superplasticity involves the knowledge of appropriate c...
