Single‐source precursor synthesis of a compositionally complex early transitional metal nitride (V, Nb, Ta, Mo, W)Nx and its high temperature stability

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Compositionally complex transitional metal nitrides are an interesting class of ceramics with superior chemical, thermal, and mechanical stability, with a high potential in ultra‐high temperature applications and catalysis. The exceptionality in the properties may partly be explained as a consequence of their high configuration entropy ...

Melting point of group IV and V transition metal diborides

Journal 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;
