Durable dual-state duplex Si–HfO2 with excellent oxidation and cracking resistance

Journal of Advanced Ceramics
The lifetime of Si bond coatings in environmental barrier coatings is constrained by phase-transition-induced cracking of the SiO2 scale. In this study, Si–HfO2 dual-state duplex composite materials are proposed to address this issue by partially forming

Critical Evaluation and Thermodynamic Modeling of the RE2O3–MgO Systems (RE = All Lanthanides + Sc, Y)

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT The RE2O3–MgO binary systems provide fundamental phase‐equilibria information for high‐temperature oxide ceramics, including MgO‐based refractories modified with rare‐earth oxides and RE2O3‐based advanced ceramic materials used in semiconductor‐processing and aerospace applications. In this study, thermodynamic modeling of the RE2O3–MgO binary

Effect of Oxide Filler Chemistry on Sintering and Phase Evolution of Polymer‐Derived SiC Composites

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
This study investigates pressureless sintering and phase evolution in polymer‐derived SiC–oxide composites containing Y2Si2O₇ or Gd2Zr2O₇ fillers. The results show that oxide filler chemistry governs apparent densification, phase stability, and local microstructure, with Y2Si2O₇ behaving primarily as a passive filler and Gd2Zr2O₇ promoting reaction ...

Bonding strength of environmental barrier coatings on surface of SiC-based ceramic matrix composites

Cailiao gongcheng
SiC-based ceramic matrix composites (SiC-CMC) are an ideal material for aeroengines with high thrust/mass ratio.In order to prevent the corrosion of SiC-CMC by gas (rich in H2O and O2) in the engine, it is necessary to prepare environmental barrier ...

Environmental Barrier Coatings Deposited by Suspension Plasma Spraying

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
By taking advantages of high deposition temperature, fully crystalline, crack‐free Yb2Si2O7 EBCs were successfully obtained by suspension plasma spray. However, high amount of Yb2SiO5 phase was found in the as‐sprayed coatings. The formation mechanism of the high amount of Yb2SiO5 phase might be attributed to the high surface ration of the particle for

Reactive self-consumption strategy to suppress SiO2 phase transition-induced cracking

Journal of Advanced Ceramics
The lifetime of Si bond coats in environmental barrier coatings (EBCs) is constrained by phase transition-induced cracking at the SiO₂ scale. In this study, reactive self-consumption and lattice solid solution strategies are employed to address this ...
