Rare-earth medium-high-entropy hafnate-based ceramic material as well as preparation method and application thereof
The invention relates to the field of control rod materials, in particular to a rare earth medium-high entropy hafnate ceramic material as well as a preparation method and application thereof, and the chemical formula of the medium-high entropy rare earth hafnate ceramic material is (REaTmbDycMd) 4Hf3O12, wherein RE is selected from at least one of Tb, Ho and Gd; m is selected from Eu and/or Er, a is equal to 0.2 or 0.25 or 1/3, b is equal to 0.2 or 0.25 or 1/3, c is equal to 0.2 or 0.25 or 1/3, and d is equal to 0.2 or 0. The rare earth hafnate neutron absorption control rod material prepared by taking the medium-high entropy rare earth hafnate ceramic as a framework has excellent radiation resistance, and is a neutron control rod material with great prospects.
