Description

Oxalic Acid, Tantalum Salt is a specialized inorganic coordination compound formed from oxalic acid and tantalum. This material is valued for its unique chemical stability and its role as a precursor in advanced material synthesis. It is primarily utilized in industries focused on high-performance ceramics, specialized catalysts, and electronic component manufacturing where precise material properties are critical.

Application

• Precursor for Tantalum Oxide Ceramics: Serves as a key starting material in the sol-gel or solid-state synthesis of high-purity tantalum pentoxide (Ta2O5) for advanced ceramics and optical coatings.
• Catalyst and Catalyst Support: Used in the formulation of specialized heterogeneous catalysts for organic synthesis and petrochemical processes.
• Electronic Materials: Employed in the production of thin-film capacitors and other passive electronic components due to its ability to form high-dielectric-constant tantalum oxide layers.
• Corrosion-Resistant Coatings: Acts as an intermediate in the development of protective coatings for metal surfaces in aggressive chemical environments.
• Research & Development: A critical reagent in materials science research for developing new tantalum-based compounds and nanocomposites.
• Specialty Glass and Pigments: Used as an additive to modify the refractive index or color properties in specialty glass and ceramic pigment formulations.

Quality Control

Our Oxalic Acid, Tantalum Salt is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a series of analytical tests including assay (Tantalum content), identification by FT-IR, and control of key metallic impurities via ICP-OES. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to ensure compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
