Used as a high-performance ceramic in dental and medical implants due to its strength and biocompatibility. Commonly employed in oxygen sensors and fuel cell membranes because of its high ionic conductivity when doped. Serves as a durable abrasive in grinding and polishing applications. Utilized as a white pigment in paints, coatings, and cosmetics for its opacity and UV resistance. Acts as a support material in catalysts for chemical processing and automotive exhaust systems. Applied in thermal barrier coatings for aerospace and industrial gas turbines to protect metal components from heat. Used in nuclear reactors as a component in fuel rod cladding due to its neutron absorption resistance.
