Effect of Sintering Parameters on the Densification, Microstructure, and Mechanical Performance of ZrB2–SiC Ceramics

International Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.
This graphical abstract illustrates the systematic investigation of Spark Plasma Sintering (SPS) parameters, temperature, pressure, and dwell time, on the densification and mechanical performance of ZrB2–20 vol% SiC composites. It highlights the critical influence of powder processing history (WC vs.

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

International 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

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;

Ti3C2Tx MXene‐Zirconium Diboride Based Ultra‐High Temperature Ceramics

Advanced Science, Volume 12, Issue 23, June 20, 2025.
This study demonstrates the effectiveness of Ti3C2Tx MXenes as additives in ultra‐high‐temperature ceramics (ZrB₂), enhancing densification, reducing oxygen content, and improving mechanical properties. Through surfactant‐free electrostatic self‐assembly and spark plasma sintering, MXenes enabled the formation of a core–shell microstructure, resulting ...
