Tantalum pentoxide is also known as tantalum(V) oxide.It is a high refractive index, low absorption material useful for coatings in the near-UV to IR spectra regions.Ta2O5 is used to make capacitors in automotive electronics, cell phones, and pagers, electronic circuitry; thin-film components; and high-speed tools.
Used in the production of lithium tantalate crystal and additive in special optical glass.
