Description

Lanthanum(III) Ethoxide is a highly reactive metal alkoxide compound, serving as a crucial precursor in advanced materials synthesis. Its primary value lies in its ability to act as a clean source of lanthanum in sol-gel and chemical vapor deposition (CVD) processes, enabling precise control over material composition and structure. This product is essential for researchers and manufacturers in the electronics, catalysis, and specialty ceramics industries seeking to develop high-performance materials with tailored properties.

Application

• Precursor for Lanthanum-Containing Thin Films: Used in Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD) to produce dielectric layers (e.g., lanthanum oxide, La2O3) for next-generation semiconductor devices.
• Sol-Gel Processing: A key starting material for synthesizing high-purity lanthanum-based ceramics, glasses, and nanoparticles with controlled porosity and homogeneity.
• Catalyst and Catalyst Support: Employed in the preparation of heterogeneous catalysts for petroleum refining, automotive exhaust treatment, and organic synthesis reactions.
• Specialty Glass and Optical Materials: Used to introduce lanthanum into glass matrices to modify refractive index, dispersion, and chemical durability for high-performance lenses and optical fibers.
• Research & Development: Serves as a versatile reagent in academic and industrial labs for exploring new lanthanum-based materials, including superconductors and phosphors.
• Polymer Additive and Cross-linking Agent: Can be utilized to modify the properties of certain polymers, enhancing thermal stability or creating novel composite materials.

Quality Control

Our Lanthanum(III) Ethoxide is produced and handled under stringent conditions to ensure batch-to-batch consistency and high chemical purity. Quality is verified through a comprehensive suite of analytical techniques. A Certificate of Analysis (COA) detailing purity, metal content, and impurity profiles is provided with each shipment and is available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly hygroscopic and moisture-sensitive nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C. The container should be kept tightly sealed when not in use to prevent contact with air and moisture, which can lead to hydrolysis and oxidation.
