Ce3+ DOPED YTTRIA NANOPOWDERS FOR TRANSPARENT YTTRIA CERAMICS PREPARED BY PRECIPITATION METHOD

FunGlass School 2018/ part1_Book of Abstracts., 2018
In optics, transparency is the physical property of materials allowing light pass through it without being scattered. Transparent polycrystalline ceramic (TPC) materials have attracted a significant attention as candidates for various applications, including laser gain media in solid state lasers, electro-optical devices and scintillators. Yttria (Y2O3)

Effects of Substructure Color and Restoration Thickness on the Final Color of Ultra‐Translucent Zirconia Ceramics

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study aimed to evaluate the effects of substructure color and restoration thickness on the final color of shade‐gradient ultra‐translucent zirconia ceramics. Material and Methods A total of 180 flat‐shaped ultra‐translucent zirconia specimens (5Y‐PSZ) with thicknesses of 0.4, 0.6, and 0.8 mm (n = 60) were fabricated and

Effect of sintering cycle on the strength and translucency of multilayered zirconia

Journal of Prosthodontics, EarlyView.
Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.
