Used as a high-performance ceramic in dental implants and crowns due to its strength and biocompatibility. Commonly applied in oxygen sensors and fuel cell membranes because of its ability to conduct oxygen ions at high temperatures. Serves as a wear-resistant coating for cutting tools and industrial components. Employed in the production of refractory materials that withstand extreme heat. Utilized in sunscreen and cosmetics as a non-toxic, UV-blocking agent. Acts as a catalyst support in chemical reactions, especially in petroleum refining. Used in the manufacture of corrosion-resistant laboratory equipment and industrial linings.
