Cadmium(2+) carbonate

Cadmium(2+) carbonate is an inorganic compound with the chemical formula CCdO3 and CAS number 513-78-0. This cadmium salt has a molecular weight of 172.42 g/mol and appears as a white crystalline powder. It is classified as a highly hazardous substance with carcinogenic and mutagenic properties, requiring extreme caution in handling. The compound is subject to strict regulatory controls due to its severe health and environmental risks.

Cadmium(2+) carbonate is a white crystalline solid that is practically insoluble in water but soluble in acids. It has no characteristic odor and decomposes upon heating to release toxic cadmium oxide fumes. The compound has a density of approximately 4.3 g/cm³ and decomposes at temperatures around 500°C. It is stable under normal conditions but should be protected from acids and strong oxidizing agents.

Cadmium(2+) carbonate is primarily used in specialized industrial applications including the production of cadmium-based pigments, electroplating processes, and as a precursor for other cadmium compounds. It serves as a starting material in the manufacture of cadmium oxide and cadmium sulfide. Due to its high toxicity, its use is heavily restricted and limited to essential industrial processes where safer alternatives are not available.

Cadmium(2+) carbonate requires strict safety measures including respiratory protection with P3 filters, chemical-resistant gloves, and protective clothing. Work must be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Personnel should receive specialized training on cadmium hazards, and regular health monitoring is essential. Emergency shower and eyewash stations must be readily accessible, and eating, drinking, or smoking in work areas is strictly prohibited.

Cadmium(2+) carbonate must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials such as acids and strong oxidizers. Storage areas should be clearly marked with appropriate hazard warnings and restricted to authorized personnel only. The compound should be kept away from heat sources and direct sunlight. Secondary containment measures are recommended to prevent environmental contamination in case of container failure.

Immediate action is required for any contact with cadmium(2+) carbonate. For skin contact, remove contaminated clothing and wash thoroughly with soap and water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention. For eye contact, flush with clean water for at least 15 minutes. In case of ingestion, do not induce vomiting and seek immediate medical care. Always inform medical personnel about the specific substance involved.

Cadmium(2+) carbonate must be disposed of as hazardous waste through licensed waste management companies specializing in heavy metal disposal. The substance cannot be disposed of in regular waste streams or sewage systems due to its toxicity and environmental persistence. Disposal must comply with local, national, and EU waste regulations including the Waste Framework Directive. All disposal activities must be properly documented and traceable for regulatory compliance.

Cadmium(2+) carbonate is classified under ADR class 6.1 (toxic substances) packing group III for transport purposes. It must be packaged in UN-approved containers with proper labeling including the toxic substance pictogram and appropriate shipping names. Transport vehicles must carry emergency response information and drivers require ADR certification. The substance must be segregated from food products and incompatible materials during transport.

Cadmium(2+) carbonate is subject to extensive EU regulations including REACH registration requirements and CLP classification as Carcinogenic 1B and Mutagenic 1B. It falls under the EU's restrictions on cadmium use in various applications. The substance requires safety data sheets, worker health surveillance, and specific risk management measures. Companies must comply with occupational exposure limits and environmental discharge controls under multiple EU directives.

Cadmium(2+) carbonate is available through OYSI, a specialized European distributor of technical chemicals. Due to its highly regulated status, purchases require proper documentation including end-use declarations and proof of regulatory compliance. OYSI ensures full regulatory compliance and provides technical support for safe handling procedures. Availability may be subject to licensing requirements and regulatory approvals depending on the intended application and jurisdiction.
