    Product Description

    Nickel Carbonate Basic CAS 12607-70-4, also called nickel carbonate hydroxide, is a basic nickel salt with the formula CH4Ni3O7 and EINECS 235-715-9.

    Synonyms: Nickelous carbonate basic; Nickel carbonate hydroxide; Nickel(II) carbonate basic; Carbonic acid nickel salt basic; Nickelous carbonate.

    CAS: 12607-70-4.

    Molecular formula: CH4Ni3O7.

    It is a fine light-green crystalline powder with bulk density about 0.65-0.90 g/cm³ and D50 particle size about 3.0-8.0 µm.

    Nickel (Ni) content is not less than 45.0%, typically 45.5-48.0%, with acid-insoluble matter not more than 0.01%.

    Trace impurities: Fe not more than 0.001%, Cu and Zn not more than 0.0005% each, Pb not more than 0.001%, Co not more than 0.005%.

    Sulfate and chloride are each not more than 0.01%; it is insoluble in water (0.093 g/L at 25 °C) and dissolves rapidly in HNO3, HCl, and H2SO4.

    In electroplating it adjusts pH and replenishes nickel ions in Watts-type baths without introducing chloride or sulfate imbalance.

    In catalyst production it is a high-purity raw material for hydrogenation and nickel-based refining catalysts.

    In ceramics and glass it is a coloring agent for glazes, ceramic pigments, and glass decolorization.

    In chemical synthesis it is an intermediate for nickel sulfamate, nickel nitrate, and nickel acetate.

    Store in a cool, dry, well-ventilated warehouse with containers tightly sealed, away from strong acids and food-grade materials.

    Wear chemical-resistant nitrile gloves, safety goggles with side shields, and an N95-equivalent dust respirator; use protective work clothing.

    Use adequate local exhaust ventilation and avoid generating dust during transfer or bag opening.

    Every batch is checked by ICP for trace metals and precise titration for nickel content, cross-referenced to high-purity industrial standards.

    Confirm appearance, nickel content, trace impurities, sulfate, chloride, particle size, packaging, and grade as required.

    FAQ - Technical & Supply Chain

    • Q:

      What is Nickel Carbonate Basic CAS 12607-70-4?

      A: CAS 12607-70-4 identifies basic nickel carbonate, also called nickel carbonate hydroxide or nickelous carbonate basic. It is a fine light-green crystalline powder containing carbonate and hydroxide groups rather than the neutral nickel carbonate form.
    • Q:

      How is basic nickel carbonate used in electroplating?

      A: It is mainly used to adjust pH and replenish nickel ions in nickel plating baths, including Watts-type baths. Because it dissolves in acidic plating solutions, it can neutralize excess acidity without introducing chloride or sulfate imbalances.
    • Q:

      What are the other major applications of Nickel Carbonate Basic?

      A: It serves as a high-purity raw material for nickel salts and nickel-based catalysts, and is used in ceramic pigments, glass coloring, and specialty nickel-containing products. Some grades are also used in nickel-based battery and coating applications.
    • Q:

      What typical specifications apply to this nickel carbonate basic grade?

      A: Industrial and electroplating grades usually specify nickel content around 45-48%, with low limits for iron, copper, zinc, lead, cobalt, sulfate, and chloride. The powder is typically light green, insoluble in water, and readily soluble in dilute mineral acids.
    • Q:

      Why choose basic nickel carbonate instead of nickel oxide for bath correction?

      A: Basic nickel carbonate dissolves more readily in acidic plating solutions at lower temperatures than nickel oxide. This makes it a practical way to raise pH and add nickel while avoiding unwanted anions in the bath.
