Tantalum Pentoxide

1. General description of Tantalum Pentoxide

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.

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.

2. Applications for Tantalum Pentoxide?


It is used for the single crystal of lithium niobate and the manufacture of high refractive and special optical glass with low dispersion. It can be used as a catalyst in chemical industry. It is a raw material for the production of crystals such as LT and LN. LT and LN are important piezoelectric, thermoelectric and nonlinear optical materials and have important applications in laser and microsonic surface wave technologies.
