MSE PRO™ 3N5 (99.95%) Tantalum Pentoxide (Ta₂O₅) Tablets (1-6mm) Evaporation Materials

Tantalum pentoxide (Ta₂O₅) is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid. It is used for optical coating due to its high refractive index and low absorption. Tantalum pentoxide thin film is also extensively used in the production of capacitors, due to its high dielectric constant.
