3. Use and Manufacturing

3.1 Description

Cobalt(II) carbonate hydroxide, with the chemical formula CoCO3·Co(OH)2, has the CAS number 12602-23-2. It appears as a pink solid with no odor. The basic structure of Cobalt(II) carbonate hydroxide consists of one cobalt atom bonded to one carbonate ion and one hydroxide ion. This compound is insoluble in water. Cobalt(II) carbonate hydroxide is considered to be harmful if swallowed and may cause skin irritation. It is also toxic to aquatic life with long-lasting effects. Therefore, precautions should be taken to prevent its release into the environment, as it can contaminate water sources and harm aquatic organisms.

Applicable Fields

Catalysis: Cobalt(II) carbonate hydroxide is used as a catalyst in various chemical reactions. Its purpose in this field involves its ability to increase the rate of a reaction without being consumed in the process. The mechanism of action in catalysis is based on the cobalt ions facilitating the formation of reactive intermediates and lowering the activation energy of the reaction.

Pigments: This compound is also used as a pigment in the production of ceramics, paints, and inks. Its purpose in this field is to provide color and enhance the visual appeal of the final product. The mechanism of action in pigments involves the absorption and reflection of specific wavelengths of light, resulting in the perception of color.

Storage

Conditions: Store in a cool and dry place.
