Description

Tantalum(5+) Oxalate is a high-purity inorganic salt of tantalum and oxalic acid, serving as a critical precursor material in advanced manufacturing. Its primary value lies in its ability to decompose cleanly at elevated temperatures, providing a reliable source of tantalum oxide. This compound is essential for industries requiring precise deposition of tantalum-based films and coatings, particularly in electronics and specialized ceramics. Manufacturers and R&D facilities utilize it for its consistent performance and purity in demanding technical applications.

Application

• Precursor for the Chemical Vapor Deposition (CVD) or Atomic Layer Deposition (ALD) of tantalum pentoxide (Ta2O5) thin films.
• Raw material for the synthesis of high-purity tantalum metal powders via thermal decomposition and reduction processes.
• Starting material in the production of advanced dielectric ceramics and electronic components like capacitors.
• Intermediate in the manufacture of specialty catalysts used in organic synthesis and petrochemical refining.
• Used in research and development for novel tantalum-containing compounds and materials science applications.
• Potential use in the formulation of corrosion-resistant coatings for specialized industrial equipment.

Quality Control

Our Tantalum(5+) Oxalate is produced under strict quality management protocols to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes comprehensive analysis, including assay for tantalum content, oxalate content verification, and trace metal impurity profiling via ICP-OES/MS. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full transparency and compliance with your material specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept sealed in a low-humidity environment to prevent moisture absorption and caking. Keep away from incompatible materials such as strong oxidizers.
