The Uses of TANTALUM ETHOXIDE

Tantalum(V) ethoxide precursor is used to deposit ultra thin films of Tantalum oxide and other tantalum containing films by atomic layer deposition and chemical vapor deposition methods

The Uses of TANTALUM ETHOXIDE

Tantalum(V) ethoxide acts as a precursor used in the preparation of ultra thin films of tantalum oxide and other tantalum containing films, which finds application in semiconductors. It is also used to prepare tantalum oxide nanoparticles for the imaging cartilage.

General Description

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.

Purification Methods

Purify it by distillation under reduced pressure. It aggregates in *C6H6,EtOH, MeCN, pyridine and diisopropyl ether. [Bradley et al. J Chem Soc 726 1955, Bradley et al. J Chem Soc 5 1956, Beilstein 1 IV 1312.]
