Description

General description

Tantalum pentoxide is dielectric in nature making it useful for making capacitors in the electronics industry.

Application

Tantalum oxide is intermixed with silicon in gate dielectric structures. It may be used to synthesize hexagonally packed mesoporous tantalum oxide molecular sieves.Ion-beam sputter deposition of tantalum oxide films was investigated for possible optical coating applications.It may be used in making optical glass for lenses and in electronic circuits.
