Description

Lithium Tantalum tert-Butoxide is a highly specialized metal-organic compound used as a critical precursor in advanced materials synthesis. This compound matters for its ability to deliver precise lithium and tantalum stoichiometry in the production of high-performance ceramics and thin films. It is essential for researchers and manufacturers in the electronics, photonics, and specialty catalyst industries seeking to develop next-generation materials with controlled properties.

Application

• Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD): A key precursor for depositing lithium tantalate (LiTaO3) and other complex oxide thin films for integrated optics, piezoelectric devices, and ferroelectric memory.
• Sol-Gel Processing: Used in the synthesis of high-purity lithium tantalate powders and gels for the fabrication of optical waveguides, non-linear optical crystals, and electro-optic modulators.
• Advanced Ceramics: Serves as a starting material for producing fine-grained, homogeneous LiTaO3 ceramics with tailored dielectric and piezoelectric properties.
• Catalysis Research: Investigated as a catalyst or catalyst precursor in specialized organic transformations and polymerization reactions due to its Lewis acidic character.
• Materials Science R&D: Employed in academic and industrial laboratories for developing novel mixed-metal oxide materials for energy storage and sensor applications.

Quality Control

Our Lithium Tantalum tert-Butoxide is produced and handled under stringent conditions to ensure batch-to-batch consistency and high purity, which is critical for sensitive deposition processes. Quality is verified through advanced analytical techniques including NMR, FT-IR, and elemental analysis (Li/Ta content). A comprehensive 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. This material is hygroscopic (moisture-sensitive) and easily oxidized; it must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. All handling should be performed in a moisture-free, inert glovebox or using strict Schlenk line techniques.
