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

Tantalum pentoxide, also known as tantalum(V) oxide, is the inorganic compound with the formula Ta2O5. It is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid. Ta2O5 is an inert material with a high refractive index and low absorption (i.e. colourless), which makes it useful for coatings. It is also extensively used in the production of capacitors, due to its high dielectric constant.

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.

c) Films are also sometimes used for dielectrics in film capacitors and as gate insulators in large scale integrated circuits requiring low leakage voltage characteristics.
