Research on multi-principal element materials has expanded exponentially to include compounds with various structures and properties with the promise of discovering unique property combinations and advanced applications. The area of compositionally complex ceramics, otherwise known as high entropy oxides, is a particular subset of this research that is showing continuous growth in the number of possible compositions that can be synthesized and characterized. High entropy pyrochlore oxides have recently gained recognition for their low thermal conductivity and tunable mechanical capabilities, but further investigation of their properties compared to standard pyrochlores is still warranted. Our group has successfully grown and characterized large, bulk single crystals of high entropy titanate pyrochlore oxides to determine their mechanical and radiation resistant properties. Resonant ultrasound spectroscopy, Raman spectroscopy, electron microscopy and ion-channeling have been employed in this study. The results obtained on these multi-component pyrochlores are compared to those of their single-component counterparts.
