| titleOfInvention | A kind of high-entropy stable rare earth tantalate/niobate ceramic and preparation method thereof |
| abstract | The invention discloses a high-entropy stable rare earth tantalate/niobate ceramic and a preparation method thereof, comprising the following steps: using rare earth oxide RE 2 O 3 , tantalum oxide Ta 2 O 5 , niobium oxide Nb 2 O 5 and MO 2 oxides are used as raw materials, and A 3 BO 7 rare earth tantalum/niobate RE 3 Ta 1- x Nb x O 7 ceramics are used as the matrix, and three or more MO 2 oxides are added to the A and B positions The rare earth and tantalum/niobium elements at the same amount are substituted to obtain a new type of high-entropy stable rare earth tantalate/niobate ceramic material RE 3‑y Ta 1‑y/2‑x Nb x‑y/2 M 2y O 7 . The ceramic material prepared by the invention has the characteristics of low thermal conductivity, high thermal expansion coefficient, high hardness, high fracture toughness and controllable crystal structure, etc., and can be used as high temperature protective materials such as thermal barrier coating, environmental barrier coating and nuclear material storage. use. |
