Microstructure, mechanical, and thermal properties of compositionally complex (Hf,Zr,Nb,Ti)B2‒LaB6 ceramics

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Novel compositionally complex borides, (Hf,Zr,Nb,Ti)B2 and (Hf,Zr,Nb,Ti)B2‒LaB6, were fabricated using spark plasma sintering process. (Hf,Zr,Nb,Ti)B2‒LaB6 exhibits a dual‐phase microstructure, in which (Hf,Zr,Nb,Ti)B2 is a primary phase with the hexagonal structure and LaB6 is a secondary phase with a cubic structure.

Melting point of group IV and V transition metal diborides

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
The environmental conical nozzle levitator system enables cooling trace experiments above 4000 K. These cooling trace experiments were used to determine the melting points through observation of thermal arrest of group IV and V transition metal diborides (TiB2, Tm = 3313 ± 33 K; ZrB2, Tm = 3404 ± 38 K; HfB2, Tm = 3529 ± 33 K; and TaB2, Tm = 3284 ± 10 K;

A unified thermo‐chemo‐mechanical model for passive, active, and interfacial oxidation of silicon carbide

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract Silicon carbide (SiC) is a promising material for hypersonic thermal protection systems, but its complex oxidation behavior—marked by transitions between passive, active, and interfacial bubbling regimes—can lead to catastrophic failure. Existing SiC models typically focus exclusively on either passive or active oxidation.

Combustion synthesis of ultra‐high temperature ceramics: Review

open access: yesInternational Journal of Applied Ceramic Technology, Volume 22, Issue 6, November/December 2025.
Abstract Novel and future‐oriented aerospace, energy, transportation, and other industrial technologies require materials capable of operating at temperatures above 2000°C. Ultra‐high temperature ceramic materials (UHTCs), based on carbides, borides, carbonitrides, and nitrides of transition metals—many with melting points exceeding 3000°C—possess the ...
