Questions And Answer | Back Directory | [Description]
Tantalum ethoxide can be used for the manufacture of tantalum (V) oxidethin-film materials using chemical vapor deposition, atomic layer deposition, and sol-gel processing. Those materials have applications in semiconductor, electrochromic and optical fields1,2,3. In research filed, it can be used for the synthesis of some novel compounds such as oxo-alkoxide-carboxylates like Ta4O4(OEt)8(OOCCH3)4 with special molecular structure2. It is also used to prepare tantalum oxide nanoparticles for the imaging cartilage4.

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 | [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.] |
