Description

Tantalum(V) Chloride CAS NO 7721-01-9 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 product is essential for manufacturers and research institutions in the semiconductor, optical coating, and specialty catalyst industries.

Application

• Chemical Vapor Deposition (CVD) & Atomic Layer Deposition (ALD): A key precursor for depositing tantalum, tantalum nitride (TaN), and tantalum pentoxide (Ta₂O₅) thin films on semiconductor wafers as diffusion barriers and high-k dielectric layers.
• Optical Coatings: Used to produce high-refractive-index tantalum oxide coatings for precision lenses, laser optics, and anti-reflective coatings.
• Catalyst Synthesis: Acts as a starting material for synthesizing Ziegler-Natta type catalysts and other organometallic complexes used in polymerization and organic synthesis.
• Ceramics & Advanced Materials: A raw material for producing tantalum-containing ceramics, composites, and specialty glasses with high thermal and chemical stability.
• Research & Development: Employed in academic and industrial labs for developing new materials, including superconductors and corrosion-resistant alloys.
• Surface Treatment: Used in specialized surface modification processes to enhance the hardness, wear resistance, and corrosion resistance of metal substrates.

Quality Control

Our Tantalum(V) Chloride is manufactured under controlled conditions to ensure high purity and batch-to-batch consistency, meeting the stringent requirements of the electronics and advanced materials industries. Each lot undergoes rigorous analytical testing, including assay and trace metal analysis, to confirm compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., argon or nitrogen) to prevent hydrolysis and degradation. Store away from strong acids and organic solvents.
