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.

Synthesis of rod-like ZrB2 under concentrated solar radiation

open access: yesMaterials Research Express
Rod-like zirconium diboride (ZrB _2 ) was synthesized for the first time using concentrated solar energy. The process involved the preparation of a Zr/O/C/B complex by sol–gel preparation at 120 °C, followed by carbothermic reduction in a quartz-windowed
