Description of Pentaethoxytantalum
Tantalum(V) ethoxide is an metalorganic compound with formula Ta2(OC2H5)10, often abbreviated as Ta2(OEt)10. It is a colorless solid that dissolves in some organic solvents but hydrolyzes readily. In solution, it aggregates to form bioctahedral dimers with composition [(EtO)4Ta(μ-OEt)]2. Several approaches for preparing tantalum(V) ethoxide are known but salt metathesis from tantalum(V) chloride is generally the most successful synthetic approach. It is mainly used for the manufacture of tantalum(V) oxide thin-film materials by approaches including chemical vapor deposition, atomic layer deposition, and sol-gel processing. These materials have semiconductor, electrochromic, and optical applications.

What is TANTALUM ETHOXIDE?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is TANTALUM ETHOXIDE which has developed particularly rapidly in recent years. Do you know about TANTALUM ETHOXIDE?
- The official answer: Ethanol tantalum(V), also known as ethanol tantalum, is an organic raw material with molecular formula C10H25O5Ta and molecular weight of 406.2901.
What’s the application of TANTALUM ETHOXIDE?
- Ethanol tantalum can be used to prepare tantalum oxide or metallic tantalum coatings by chemical vapor deposition (CVD) deposition; hydrolysis of ethanol tantalum followed by heating can also produce tantalum oxide powder, which can produce high purity grades of tantalum oxide.
- High specific area tantalum oxide films have been produced in the United States using ethanolic tantalum as a precursor. These films exhibit good optical activity and have potential applications in solar cells and photocatalysts.
- Ethanol tantalum can be used in plasma technology to generate ultrafine tantalum carbide powders.
- The main application of ethanol tantalum for surface coating is the preparation of tantalum nitrideChemicalbook or tantalum oxide. Because of their high dielectric properties and stability, tantalum nitride and tantalum oxide are mainly used in the protective and dielectric layers of electronic components.
- Tantalum ethoxide produces tantalum nitride in circuit boards with a high melting point and a structure of micro grains. This nitride layer structure in the circuit board allows the diffusion of copper in contact with silicon or silicon dioxide to be inhibited.
- In addition, it has also been noted that tantalum nitride can tolerate higher temperatures than other barrier metals without degradation, making tantalum with ethanol tantalum as a precursor and tantalum nitride a superior barrier layer for copper processes.
- The main alcohol salts of tantalum are methanol tantalum, ethanol tantalum, propanol tantalum, butanol tantalum, and isobutanol tantalum. Among them, ethanol tantalum is the most widely used. The alcohol salt of tantalum can be dissolved in most organic substances, so it is an ideal precursor Chemicalbook body for tantalum oxide.
- Tantalum and most compounds of tantalum are relatively stable. Tantalum metal does not react with ethanol under usual conditions. There are currently two main methods of synthesizing ethanolic tantalum, one is the chloride chemistry method and the other is the “sacrificial” anode method.
