| Abstract Scope |
<p>
The development of materials capable of withstanding extreme environments is essential for enabling future technological advancements. High-entropy carbide (HEC) ceramics have gained attention for their outstanding thermal, mechanical, and chemical stability. In this study, the synthesis and densification of a single-phase, fully dense (Cr,Mo,Ta,V,W)C<sub>1-x</sub> ceramics were optimized at different sintering temperatures and fundamental properties were measured.
</p>
<p>
Thermal, electrical, and magnetic properties were characterized by using a physical property measurement system at both room temperature and cryogenic temperatures. The concentrations of carbon vacancies and dissolved oxygen in the lattice were quantified using neutron diffraction and inert gas fusion analysis.
</p>
<p>
The unique physical characteristics, combined with phase purity and density, demonstrate the promise of this HEC ceramic for use in extreme-temperature and high-performance applications.
