Description

Tantalum Ethoxide is a high-purity metal-organic compound, also known as tantalum(V) ethoxide, serving as a critical precursor in advanced materials synthesis. Its primary value lies in delivering a controlled, soluble source of tantalum for the fabrication of thin films and nanostructured materials with exceptional dielectric and chemical resistance properties. This product is essential for manufacturers and R&D facilities in the semiconductor, optical coating, and specialty ceramics industries seeking reliable performance in demanding applications.

Application

• Chemical Vapor Deposition (CVD) & Atomic Layer Deposition (ALD): A key precursor for depositing high-k tantalum oxide (Ta2O5) thin films in semiconductor devices and memory capacitors.
• Sol-Gel Processing: Used to synthesize tantalum-based gels for producing high-purity oxide powders, fibers, and monolithic ceramics with tailored porosity.
• Optical & Protective Coatings: Enables the production of anti-reflective, high-index, and corrosion-resistant coatings on glass, lenses, and metal substrates.
• Catalyst Synthesis: Serves as a starting material for preparing heterogeneous catalysts and catalyst supports used in selective oxidation and other chemical processes.
• Specialty Polymers & Composites: Acts as a cross-linking agent or additive to enhance the thermal stability and mechanical properties of advanced polymer matrices.
• Research & Development: A fundamental reagent for exploring new tantalum-containing materials, including mixed-metal oxides and novel coordination complexes.

Quality Control

Our Tantalum Ethoxide is manufactured under stringent conditions to ensure batch-to-batch consistency and high chemical purity. Quality is verified through a comprehensive suite of analytical techniques, including NMR, FT-IR, and elemental analysis. A Certificate of Analysis (COA) detailing purity, metal content, and solvent residues is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity.
