    Cobalt(II) Nitrate Hexahydrate CAS 10141-05-6

    Cobalt(II) Nitrate Hexahydrate is an inorganic cobalt salt commonly supplied as a chemical raw material and intermediate, also referred to in technical contexts as cobaltous nitrate hexahydrate, cobalt nitrate hexahydrate, or cobalt(II) dinitrate hexahydrate. Identified by CAS 10141‑05‑6, it consists of divalent cobalt coordinated with nitrate anions and crystallization water, enabling controlled cobalt ion availability during thermal decomposition or solution‑based reactions. The compound is typically applied as a catalyst precursor in industrial chemical processes where cobalt‑containing phases are generated under defined conditions. From a supply perspective, it is offered with competitive factory pricing, customized specifications, and complete documentation including MSDS, TDS, COA, suitable for regulated bulk supply in industrial use.

    Applications

    Catalyst Manufacturing

    • Petrochemicals: Used as a raw material for the preparation of cobalt-based catalysts supported on alumina or silica, essential for hydrodesulfurization (HDS) and Fischer-Tropsch synthesis.

    Pigments & Ceramics

    • Ceramic Colors: A key ingredient in the production of “Cobalt Blue” pigments for coloring porcelain, glass, and enamels. It provides intense, heat-stable coloration.

    Surface Treatment & Plating

    • Electroplating: utilized in cobalt electroplating baths and as an additive in nickel plating to improve hardness and brightness.
    • Corrosion Protection: Used in chemical conversion coatings for aluminum and steel.

    Electronics & Batteries

    • Battery Materials: Precursor for synthesizing cobalt oxide and other cathode materials used in lithium-ion batteries.

    Quality Assurance (QA/QC)

    Our Cobalt Nitrate is produced under strict ISO 9001:2015 protocols to ensure high metal purity and low impurity profiles.

    • Metal Analysis: We utilize ICP-OES to strictly control trace impurities like Iron (Fe), Nickel (Ni), and Copper (Cu), which can affect catalyst performance.
    • Stoichiometry: Precise control of the hexahydrate form ensures stable cobalt content (approx. 20%) for accurate formulation in downstream processes.
    • Solubility Test: Every batch undergoes solubility testing to guarantee a clear solution with no sediment.

    Storage & Safety

    Storage Guidelines

    • Oxidizer: Store separately from flammable materials, reducing agents, and organics.
    • Hygroscopic: The product absorbs moisture rapidly. Store in a cool, dry area in tightly sealed containers.
    • Temperature: Avoid high temperatures to prevent melting (approx. 55°C) and decomposition.

    Safety & PPE Recommendations

    • Hazard Class: Oxidizing Solid (Class 5.1). May intensify fire.
    • Health Hazard: May cause an allergic skin reaction and is suspected of causing cancer/genetic defects (Carcinogen Category 1B).
    • PPE: Wear full protective clothing, P3 dust mask/respirator, and chemical-resistant gloves. Avoid dust generation.
    • Environmental: Toxic to aquatic life with long-lasting effects. Prevent release to the environment.

    FAQ - Technical & Supply Chain

    • Q:

      How does the hexahydrate form differ from anhydrous cobalt nitrate?

      A: The hexahydrate contains defined water of crystallization, which affects handling, solubility, and thermal behavior compared to the anhydrous form.
