Ultra-high temperature ceramics (UHTCs) are generally referred to the carbides, nitrides,
and borides of the transition metals, with the Group IVB compounds (Zr & Hf) and TaC as the …

Ceramic materials having melting points higher than 3000° C and suitable for structural
applications at above 2000° C are commonly known as Ultra-High Temperature Ceramics …

This paper reviews the crystal chemistry, synthesis, densification, microstructure, mechanical
properties, and oxidation behavior of zirconium diboride (ZrB2) and hafnium diboride (HfB2) …

This study reviews densification behaviour, mechanical properties, thermal, and electrical
conductivities of the ZrB2 ceramics and ZrB2-based composites. Hot-pressing is the most …

Zirconium diboride (ZrB2) was densified (> 98% relative density) at temperatures as low as
1850° C by pressureless sintering. Sintering was activated by removing oxide impurities …

The processing and the properties of two ultra-high temperature ceramics (UHTCs)
designed for the manufacturing of aerospace sharp-shaped hot-structures are presented …

This work investigated suitability and efficacy of the sintering technique known as spark
plasma sintering to produce ultra‐high‐temperature‐based Hf and Zr borides. Ceramic …

Ultra high temperature ceramics (UHTCs), including ZrB 2-SiC, are designed for extreme
environment applications in which temperatures exceed 2273 K (2000° C). A key material …

ZrB 2–SiC–graphite composites with 0–35 vol% graphite flakes were densified via hot-
pressing route at the temperature of 1800° C under the uniaxial pressure of 40 MPa for 1 h …
