Cobalt(2+) carbonate

Cobalt(2+) carbonate is an inorganic chemical compound with the formula CCoO3 and CAS number 513-79-1. This cobalt salt has a molecular weight of 118.942 g/mol and appears as a crystalline solid. It is classified as a hazardous substance with multiple health and environmental concerns, including carcinogenic, mutagenic, and reproductive toxicity properties. The compound also exhibits respiratory and skin sensitization potential and poses risks to aquatic environments.

Cobalt(2+) carbonate is typically a pink to red crystalline solid at room temperature. The compound is sparingly soluble in water but dissolves in acids, releasing carbon dioxide. It has a molecular weight of 118.942 g/mol and maintains stability under normal conditions. Like other cobalt compounds, it exhibits characteristic coloration due to the cobalt(2+) ion and decomposes upon heating to release carbon dioxide and form cobalt oxide.

Cobalt(2+) carbonate is primarily used as a precursor in the production of other cobalt compounds and catalysts. It serves as a raw material in the ceramics and glass industry for producing blue and pink pigments. The compound is also utilized in the manufacture of cobalt-based catalysts for chemical processes and in the production of cobalt salts for various industrial applications. Additionally, it finds use in electroplating and as a drying agent in paints and varnishes.

Cobalt(2+) carbonate requires strict safety measures due to its classification as Carc. 1B, Muta. 2, and Repr. 1B. Always wear appropriate respiratory protection, chemical-resistant gloves, and protective clothing. Work in well-ventilated areas or use local exhaust ventilation to minimize inhalation exposure. Avoid skin contact and ingestion. Use proper hygiene practices, including washing hands thoroughly after handling. Ensure workers are trained on the hazards and emergency procedures before handling this dangerous substance.

Cobalt(2+) carbonate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials. Keep containers upright and properly labeled with hazard information. Store away from acids, strong oxidizers, and heat sources. Implement appropriate containment measures to prevent environmental release. Access should be restricted to trained personnel only. Regular inspection of storage containers is recommended to ensure integrity and prevent leakage or contamination.

Cobalt(2+) carbonate exposure requires immediate action due to its sensitizing and toxic properties. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water. In case of eye contact, rinse immediately with plenty of clean water for at least 15 minutes. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician after any exposure, providing the safety data sheet.

Cobalt(2+) carbonate must be disposed of as hazardous waste through licensed waste management companies due to its environmental and health hazards. Never dispose of this substance in regular waste streams or pour down drains. Collect waste in appropriate containers, properly labeled and segregated from other materials. Follow local and national regulations for hazardous waste disposal. Consider recovery or recycling options where available, as cobalt is a valuable metal resource.

Cobalt(2+) carbonate is classified under ADR Class 9 (Miscellaneous dangerous goods), Packing Group III. Transportation requires proper packaging in UN-approved containers with appropriate labeling and documentation. Vehicles must carry emergency response information and proper placarding. Drivers need ADR certification for dangerous goods transport. Ensure packages are properly secured to prevent damage during transit and that all shipping papers accurately reflect the hazardous nature of the material.

Cobalt(2+) carbonate is subject to comprehensive regulatory oversight under REACH, CLP, and other European chemical regulations due to its hazardous classification. The substance requires proper classification, labeling, and packaging according to CLP regulation with GHS08 and GHS09 pictograms. Users must comply with occupational exposure limits and may need authorization for certain uses. The compound's carcinogenic and reproductive toxicity properties trigger additional regulatory requirements for risk assessment and exposure control measures.
