Description

Vanadate CAS NO 13981-20-9 refers to a class of chemical compounds containing the vanadate oxyanion (VO₄³⁻), which are critical for their catalytic and electrochemical properties. These compounds are essential in industrial processes where precise control over oxidation states and ionic interactions is required. Key industries that utilize vanadates include advanced battery manufacturing, specialty glass production, and as precursors for corrosion-resistant metal coatings and catalysts.

Application

• Electrolyte Additive for Flow Batteries: Serves as a key active material in vanadium redox flow batteries (VRFBs) for large-scale energy storage systems.
• Catalyst Precursor: Used in the synthesis of oxidation catalysts for the production of sulfuric acid and maleic anhydride.
• Corrosion Inhibitor: Applied in formulations for protective coatings and cooling water treatments to prevent metal degradation.
• Glass & Ceramic Modifier: Imparts specific color (yellow, blue) and UV-blocking properties to specialty glasses and ceramic glazes.
• Biochemical Research: Acts as an inhibitor of ATPases and other phosphate-metabolizing enzymes in biochemical studies.
• Wood Preservation: Used in certain wood treatment formulations alongside other biocides.
• Photographic Developer: Employed in specific photographic and photochemical processes.
• Precursor for Functional Materials: A starting material for synthesizing vanadium oxide thin films and other advanced materials.

Quality Control

Our vanadate products are manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment. We can supply material that meets various grade requirements, including Technical, Reagent, and High-Purity grades for specific applications.

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 (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
