Thorium tantalate (ThTa₂O₇) is a complex oxide ceramic composed of thorium and tantalum elements, belonging to the family of high-density refractory oxides. This material is primarily investigated in research contexts for nuclear fuel applications, refractory coatings, and advanced ceramic matrix composites, where its high melting point and chemical stability under extreme conditions offer potential advantages over conventional oxides.
