High-entropy (Ca0.5Ce0.5)(Nb0.25Ta0.25Mo0.25W0.25)O4 scheelite ceramics with high-temperature negative temperature coefficient (NTC) property for thermistor materials

(Ca0.5Ce0.5)(Nb0.25Ta0.25Mo0.25W0.25)O4 high-entropy ceramics with single scheelite phase structure were synthesized by solid-state reactions under a reducing atmosphere of argon, and their high-temperature electrical properties were investigated. The single scheelite phase of high-entropy ceramics...
