Used extensively in the electronics industry as a high-permitting dielectric material in capacitors, enabling miniaturization and improved performance. Its stable insulating properties make it ideal for thin-film applications in semiconductors and integrated circuits.

Also employed in optical coatings due to its high refractive index, providing anti-reflective and protective layers in lenses, lasers, and mirrors.

Finds use in biomedical devices for its biocompatibility and corrosion resistance.

Additionally, serves as a catalyst support and active catalyst in certain chemical reactions, particularly in dehydration and oxidation processes.
