Product Description:Tantalum pentoxide, Ta2O5, is a high-index, low-absorption material usable for coatings in the near-UV (350 nm) to IR (~8 ?m) regions. Dense layers can be
deposited by electron-beam evaporation or sputtering. It usually decomposes at 1470 deg. C.

Typical Applications:
a) Ferroelectric properties
b) Because the index below wavelengths 300 nm is greater than 2, it can sometimes be combined in multilayers with silicon dioxide (n = 1.48) for UV laser applications. Hard, scratch-resistant and adherent coatings can be deposited.
Films are also sometimes used for dielectrics in film capacitors and as gate insulators in large scale integrated circuits requiring low leakage voltage characteristics.
