| | TANTALUM ETHOXIDE Usage And Synthesis |
| 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.
