Temperature‐controlled synthesis of bismuth tungstate with enhanced photochromic properties

International Journal of Applied Ceramic Technology, Volume 22, Issue 3, May/June 2025.
Abstract This study explores the photochromic properties of bismuth tungstate (Bi2WO6) synthesized via a solid‐state method at various temperatures (300°C–1000°C) to optimize light‐responsive behavior for potential applications. The Bi2WO6 samples, prepared from tungsten oxide (WO3) and bismuth oxide (Bi2O3) through heat treatment, were analyzed using ...

The effect of different surface treatments on the shear bond strength of new generation zirconia

International Journal of Applied Ceramic Technology, EarlyView.
Twelve zirconia subgroups were created using different material types and surface treatments. Sandblasting and tribochemical silica coating significantly improved shear bond strength. Bond strength varied based on zirconia type, surface treatment, and their interaction, emphasizing the importance of surface preparation.

Examining the effect of temperature on steam oxidized silicon bond coats

Journal of the American Ceramic Society, EarlyView.
Abstract The SiO2 thermally grown oxide (TGO) is a life‐limiting factor for environmental barrier coatings (EBCs). EBCs in aeroengines face a variety of operating temperatures so the resulting effect on SiO2’s crystallinity and growth are necessary to better understand EBC failure.

Optical and Mechanical Properties of the Multi‐Transition Zones of a Translucent Zirconia

Journal of Esthetic and Restorative Dentistry, Volume 37, Issue 2, Page 525-532, February 2025.
ABSTRACT Objective To characterize the composition, flexure resistance, and optical properties of a multilayer translucent zirconia in relation to its multi‐transition zones. Materials and Methods A multilayer zirconia (5Y/4Y) and a conventional 3 mol% yttria partially stabilized zirconia (3Y) were investigated.

Color stability of precolored and extrinsically colored monolithic multilayered polychromatic zirconia: Effects of surface finishing and aging

Journal of Prosthodontics, EarlyView.
Abstract Purpose To explore the impact of zirconia types, coloring methods, and surface finishing on the color stability of monolithic multilayered polychromatic zirconia after artificial aging, including thermocycling and simulated toothbrushing. Materials and Methods Eighty square‐shaped zirconia samples were divided into 2 types (M3Y‐TZP and M6Y‐PSZ)

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.

Low‐temperature dissociation of zircon in highly alkaline conditions: A cautionary note for studies on natural glasses of debated origin

Meteoritics &Planetary Science, EarlyView.
Abstract Dissociated zircon is largely used as a robust indicator of glasses generated by impact cratering and airbursts. The reaction of zircon dissociation, i.e. ‘ZrSiO4 → ZrO2 + SiO2’, requires high temperatures (>1670°C) only reached by extreme geological processes. Using high‐temperature experiments, this study shows that zircon can dissociate and
