설명

일반 설명

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.

애플리케이션

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.
