Used as a high-performance ceramic in dental implants and crowns due to its strength and biocompatibility. Commonly employed in oxygen sensors and fuel cell membranes because of its ability to conduct oxygen ions at high temperatures. Serves as a refractory material in furnace linings and crucibles owing to its high melting point and chemical stability. Applied as a white pigment in paints, coatings, and cosmetics for its opacity and resistance to UV degradation. Utilized in the production of abrasion-resistant coatings and industrial cutting tools. Acts as a catalyst or catalyst support in petroleum refining and chemical synthesis processes. Used in nuclear reactors as a component in control rods and structural materials due to its neutron absorption properties.
