Behavior of copper oxide in silicoborate glazed glasses [PDF]

, 2007
Copper-containing glazed glasses in the B[2]O[5] - SiO[2] – Al[2]O[3] – CaO – CuO system with a copper oxide molar content of 5 to 25%, added during synthesis of the glasses, was investigated.

Effect of substructure fabrication method and design on the fracture resistance properties of metal–ceramic restorations

Journal of Prosthodontics, EarlyView.
Abstract Purpose In metal–ceramic restorations, the substructure fabrication method and design may affect the prognosis of the prosthesis. This study evaluated and compared the fracture resistance of metal–ceramic restorations fabricated with different substructure fabrication methods using two different alloy powders and designs.

Zirconium titanate ceramic pigments: Crystal structure, optical spectroscopy and technological properties [PDF]

, 2006
Srilankite-type zirconium titanate, a promising structure for ceramic pigments, was synthesized at 1400 degrees C following three main doping strategies: (a) ZrTi(1-x)A(x)O(4), (b) ZrTi(1-x-y)A(x)B(y)O(4) and (c) Zr1-xCTiO4 where A = Co, Cr, Fe, Mn.

Optical stability of 3D‐printed and milled zirconia after artificial aging and immersion in liquids: An in vitro study

Journal of Prosthodontics, EarlyView.
ABSTRACT Purpose To assess the impact of artificial aging and immersion in common liquids on the optical properties of 3D‐printed and milled zirconia. Materials and Methods Monolithic zirconia discs (N = 100) were fabricated using two methods: 3Y‐TZP for milling (e.max ZirCAD LT BL, Ivoclar Vivadent) and printable 3Y‐TZP material (LithaCon 3Y 230) for ...

Iron and chromium doped perovskite (CaMO3 M = Ti, Zr) ceramic pigments, effect of mineralizer [PDF]

, 2012
Solid solutions Ca(DxM1−x)O3 (M = Ti, Zr and D = Fe,Cr), have been studied as ceramic pigment in conventional ceramic glazes using 0.5 mol/mol of NH4Cl as flux agent by solid state reaction and by ammonia coprecipitation route.

Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?
