Description

Tantalum Chloride (CAS NO 39455-50-0) is a high-purity inorganic compound that serves as a critical precursor in advanced materials synthesis. Its primary value lies in its role as a versatile source of tantalum for depositing thin films and synthesizing specialty chemicals. This material is essential for manufacturers and research institutions in the semiconductor, optical coating, and catalysis sectors seeking reliable, high-quality metalorganic precursors.

Application

• Chemical Vapor Deposition (CVD) & Atomic Layer Deposition (ALD): As a key precursor for depositing tantalum-containing thin films, such as tantalum nitride (TaN) and tantalum pentoxide (Ta₂O₅), used in semiconductor gate dielectrics and diffusion barriers.
• Optical Coatings: Used in the production of high-refractive-index coatings for precision lenses, laser optics, and anti-reflective layers.
• Catalyst Synthesis: Acts as a starting material or co-catalyst in organic synthesis and polymerization reactions.
• Ceramics & Advanced Alloys: A raw material for producing specialty tantalum-based ceramics and metal alloys with high melting points and corrosion resistance.
• Research & Development: Employed in academic and industrial labs for developing new materials, including superconductors and battery components.
• Surface Treatment: Used in surface modification processes to enhance hardness, wear resistance, and chemical stability of substrates.

Quality Control

Our Tantalum Chloride is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including titration, ICP-OES, and X-ray diffraction. A Certificate of Analysis (COA) detailing purity, impurity profiles, and physical characteristics is provided with each shipment to ensure compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (e.g., argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C to maintain stability and prevent decomposition. Keep away from strong acids and organic solvents.
