Description

Tantalum (V) Isopropoxide is a high-purity metal-organic compound, also known as tantalum pentaisopropoxide, serving as a critical precursor in advanced materials synthesis. Its primary value lies in delivering high-purity tantalum sources for the fabrication of specialized thin films and ceramic materials. This product is essential for manufacturers and R&D facilities in the semiconductor, optical coating, and specialty ceramics industries.

Application

• Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD): A key precursor for depositing high-quality tantalum oxide (Ta2O5) thin films used in dynamic random-access memory (DRAM) capacitors and gate dielectrics.
• Sol-Gel Processing: Used to synthesize tantalum-based sols for producing high-refractive-index optical coatings, anti-reflective layers, and waveguides.
• Specialty Ceramics and Catalysts: Acts as a starting material for producing advanced tantalum-containing ceramics and as a catalyst or catalyst support in specialized organic reactions.
• Nanomaterials Research: Employed in the bottom-up synthesis of tantalum oxide nanoparticles and nanostructures for sensing and energy applications.
• Protective Coatings: Used to develop thin, corrosion-resistant coatings on metals and other substrates for demanding industrial environments.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, this material must be stored under an inert atmosphere (e.g., argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids and oxidizing agents.
