Low-Temperature Synthesis of Ta_xHf_1−xC Solid Solutions via Pectin Gelation: Phase and Morphological Evolution

Inorganics
Ultra-high-temperature ceramics (UHTCs) in the Ta–Hf–C ternary system are of significant interest for extreme aerospace and energy applications due to their melting points near 4000 °C. However, their synthesis typically requires extreme temperatures and

Synthesis, processing and characterization of ZrB (suíndice 2)-based ultra high temperature ceramics (UHTC) for aerospace applications

, 2009
The high melting temperature of ultra-high temperature ceramics (UHTCs) makes ZrB2-based composites potential candidates for aerospace applications. Full densification of these composites faces major challenge due to the strong covalent bonding and the high-melting point, although with additions of SiC, ZrC, MoSi2, etc. densification can be achieved at
