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;
