Cobalt Carbonate, identified by its CAS number 513-79-1, is a chemical compound with distinct properties that dictate its utility across various industrial sectors. Understanding these cobalt carbonate chemical properties is fundamental for manufacturers and researchers utilizing this compound in their processes.

The appearance of Cobalt Carbonate is typically described as a blue or pink powder. This color is characteristic of cobalt(II) compounds. Its molecular formula is CoCO3, and it has a molecular weight of 118.94 g/mol. A key specification for its industrial use is its Cobalt content, which is generally assayed at ≥47%. This high percentage of cobalt is what makes it a valuable precursor and additive in many applications.

In terms of solubility, Cobalt Carbonate is insoluble in water, a common trait for many metal carbonates. However, it readily reacts with mineral acids, dissolving to form the corresponding cobalt(II) salt, water, and carbon dioxide. This reactivity is often exploited in chemical synthesis and purification processes. For example, the preparation of Cobalt Carbonate itself often involves precipitating it from solutions of cobalt(II) salts using carbonate or bicarbonate ions.

The typical properties table for Cobalt Carbonate often lists other important specifications alongside the cobalt content, such as limits for impurities like Nickel, Iron, Magnesium, and Calcium, which are usually kept to very low levels (e.g., ≤0.01%). These low impurity levels are critical for applications where even trace amounts of other metals can interfere with catalytic activity or pigment quality.

For those looking to buy Cobalt Carbonate, ensuring these specifications are met by the supplier is vital. The CAS 513-79-1 designation guarantees the specific chemical entity being discussed, but the detailed properties listed on a Technical Data Sheet (TDS) or Certificate of Analysis (COA) provide the crucial information for application suitability. Whether used as a catalyst precursor, a pigment, or a mineral supplement, the precise chemical makeup of Cobalt Carbonate is its primary asset.
