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 discoloration. Utilized in abrasives and grinding media for its hardness and wear resistance. Functions as a catalyst or catalyst support in chemical processing and automotive exhaust systems. Used in the production of wear-resistant coatings and thermal barrier coatings on metal components. Employed in nuclear reactors as a component in control rods and fuel cladding due to its neutron absorption properties.
