Experimental investigation of fifth oxide effects on calcium–magnesium–aluminosilicate glass properties

open access: yesInternational Journal of Applied Glass Science, EarlyView.
Abstract Molten calcium–magnesium–aluminosilicate (CMAS) containing debris is a leading threat to hot‐section components in air‐ingesting turbine engines. This study investigated common natural‐forming and coating‐derived oxide additions to CMXAS glasses—where X denotes a fifth oxide constituent.

Tailoring strength and ionic conductivity in zirconia‐based solid oxide electrolytes using a multimaterial approach

open access: yesJournal of the American Ceramic Society, EarlyView.
Abstract A multimaterial approach is explored for tailoring the mechanical and functional properties of zirconia‐based ceramic electrolytes to be employed in electrochemical solid oxide cells (SOCs). The combination of alumina‐toughened zirconia (ATZ) surface layers with an embedded 8 mol% yttria‐stabilized zirconia (8YSZ) core layer introduces ...

Plasma‐flash sintering II: Flashing ZnO at room temperature using low AC voltage

open access: yesJournal of the American Ceramic Society, EarlyView.
Abstract In this study, we have advanced the plasma‐flash sintering (PFS) technique by demonstrating the preparation of dense ZnO ceramics at room temperature using a moderate electric field of 250 V cm−1 under a low‐pressure nitrogen atmosphere. This specific environment facilitates the sequential occurrence of plasma generation followed by the flash ...

Yttria magnesia co-stabilized zirconia refractories for application as functional components in continuous steel casting

open access: yesOpen Ceramics, 2023
Zirconia is one of the most promising functional refractory materials in continuous steel casting and is employed in areas with high thermal and chemical stresses such as the slag line, the nose of monoblock stoppers or the inlet area of submerged entry ...

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

open access: yesJournal 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)
