Descrição geral

Tantalum(V) ethoxide Ta(OC2H5)5 is a tantalum alkoxide that can be used as a precursor in the preparation of tantalum oxide by chemical vapor deposition (CVD). It has excellent volatility and thermal stability. It can be synthesized by anodic oxidation of tantalum plate in anhydrous ethanol.

Aplicação

Ta(OC2H5)5 can be used in the formation of ultrathin tantalum oxide based capacitors. It can also be used as a liquid precursor in the preparation of tantalum carbide nanopowder for hard coating on metal surfaces.
