Synthesis process, elastic/thermal properties and potential application of CrTaO4

Caption

The CrTaO4 powder and bulk CrTaO4 were synthesized by solid state reaction and hot-press sintering, respectively. Using HAADF and ABF-STEM techniques, the rutile crystal structure of CrTaO4 was confirmed and short-range order was directly observed. Intriguingly, on the ground of moderate thermal expansion coefficient, low thermal conductivity, CrTaO4 is expected a new thermal barrier material for refractory metals and their alloys, refractory high entropy alloys and ultrahigh temperature ceramics.
