CERIUM CARBONATE 

1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

2. CHEMICAL STRUCTURE

2.1. Molecular Structure

Cerium carbonate is the carbonate salt of cerium in the +3 oxidation state. Cerium ions (Ce³⁺) and carbonate ions (CO₃²⁻) are present in a 2:3 ratio. The compound is insoluble in water but soluble in dilute acids. It is stable at room temperature and exhibits neutral to slightly basic pH in suspension.

Structural Features:

18. CRITICAL NOTICES AND BEST PRACTICES

CRITICAL NOTICES:

1. Environmental Hazard: Cerium carbonate is classified as an environmentally hazardous substance (UN 3077). May cause long-lasting harmful effects to aquatic life (H413).

2. Acid Sensitivity: Dissolves in dilute acids with CO₂ evolution. Should be kept away from acids.

3. Dust Control: Dust may cause respiratory irritation. Use appropriate dust control measures.

4. Precursor Material: Primarily used as a precursor for CeO₂ production and glass polishing applications.

5. Inhalation Hazard: Dust may cause respiratory irritation. Use in well-ventilated areas.

6. Food/Cosmetics Prohibited: Not approved for food or cosmetic applications.

BEST PRACTICE RECOMMENDATIONS:

Storage:

• Store in a cool, dry, well-ventilated area

• Use sealed, moisture-proof containers

• Keep away from acids

• Store at room temperature (15-25°C)

Handling:

• Use in well-ventilated areas

• Use dust mask, protective goggles, and gloves

• Avoid dust formation

• Wash hands after handling

Waste Management:

• Dispose in accordance with local regulations

• Do not discharge into water bodies

• Consider rare earth recovery for large quantities
