Abstract
In the last years, high entropy ceramics (HECs) compounds have attracted significant attention due to their unique chemical compositions and crystal structure which make them potentially useful functional materials. One of them is the RGa1/3Ti2/3O10/3 (R: rare earth element) ceramic layered compound, which comes from the pseudo-binary system RGaO3–R2Ti2O7 partial solid solution. In this work, we design a single phase of (Lu0.2Yb0.2Tm0.2Er0.2Ho0.2)Ga1/3Ti2/3O10/3 high entropic ceramic compound. This compound was synthesized by the solid-state reaction method and employing several thermal treatments at high temperatures. The phase stability was determined using X-ray powder diffractometry analysis (XRD). The morphology and cation distribution in the samples were identified using scanning electron microscopy (SEM) and elemental mapping. In addition, the dielectric behavior of samples exposed under several heating treatments is presented.
