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 sunscreen and cosmetics as a non-toxic, reflective pigment that blocks UV light. Utilized in water purification systems to remove contaminants through adsorption and catalytic processes. Acts as a stabilizer in pigment formulations and thermal barrier coatings in aerospace applications.
