Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation

European Journal of Oral Sciences, EarlyView.
Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).

Rapid sintering of 1.5 mol% yttria stabilized 3D-printed zirconia

European Journal of Materials
The widely use of 3 mol% yttria stabilized zirconia (3YSZ) in technical applications is driven by the toughening effect provided by the tetragonal to monoclinic phase transformation during mechanical loading.

Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Atomically ordered solute segregation behaviour in an oxide grain boundary

Nature Communications, 2016
Solute segregation is challenging to experimentally identify at the atomic scale. Here, the authors report the direct observation of atomic site-dependent solute segregation behaviour in an yttria-stabilized zirconia grain boundary by atomic-resolution ...

Effect of Glazing Dwell Time and Cooling Duration on Flexural Strength and Surface Microhardness of 3 mol% Yttria‐Stabilized Tetragonal Zirconia: An In Vitro Study

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of glazing dwell time and cooling duration on the flexural strength and surface microhardness of high‐translucency 3 mol% yttria‐stabilized tetragonal zirconia polycrystal (3Y‐TZP). Materials and Methods Total of 108 rectangular zirconia specimens (20 × 4 × 2 mm) were fabricated from preshaded monolithic blocks
