Cobalt Sulphate

Description:

Cobalt Sulphate is an inorganic compound that typically occurs as a red-pink crystalline solid in its heptahydrate form. It is highly soluble in water and slightly soluble in ethanol. Cobalt Sulphate is commonly used in electroplating, as a precursor to cobalt pigments, and as an additive in animal feed to provide essential cobalt nutrients. It is also used in battery manufacturing and as a catalyst in various chemical processes.

Physical Properties:

• Appearance: Red to pink crystalline solid
• Melting Point: Decomposes at 735°C (anhydrous form)
• Density: 2.03 g/cm³ (heptahydrate)
• Solubility: Soluble in water, slightly soluble in ethanol

Applications:

• Electroplating: Used in cobalt electroplating to provide a hard, corrosion-resistant, and bright surface coating.
• Battery Manufacturing: A key component in the production of lithium-ion batteries, particularly in the cathode materials for rechargeable batteries.
• Ceramics and Pigments: Used in the manufacture of cobalt-based pigments, which impart a blue hue to ceramics and glass.
• Animal Feed Additive: Provides essential cobalt, necessary for the health of ruminants, as part of their vitamin B12 production.
• Catalyst: Employed in chemical reactions where cobalt acts as a catalyst, particularly in the petrochemical and organic synthesis industries.

Handling and Storage:

• Handling: Use proper personal protective equipment, including gloves, goggles, and protective clothing. Ensure adequate ventilation during use. Avoid inhaling dust and direct contact with skin and eyes.
• Storage: Store in a cool, dry, and well-ventilated area, away from incompatible substances like strong reducing agents. Keep containers tightly sealed when not in use to prevent moisture absorption.

Hazards and Precautions:

• Hazard Statements:
  • Harmful if swallowed or inhaled.
  • May cause skin, respiratory, and eye irritation.
  • May cause an allergic skin reaction.
  • Suspected of causing cancer.
  • Toxic to aquatic life with long-lasting effects.
• Precautionary Statements:
  • Avoid breathing dust, fumes, or vapors.
  • Wear appropriate protective gear, including gloves, protective clothing, and eye protection.
  • Do not allow product to reach waterways, as it can be hazardous to aquatic environments.

Safety Measures:

• First Aid:
  • Inhalation: Move to fresh air immediately. Seek medical attention if symptoms such as respiratory discomfort persist.
  • Skin Contact: Wash thoroughly with soap and water. Remove any contaminated clothing and seek medical attention if irritation develops.
  • Eye Contact: Rinse eyes cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing and seek medical help.
  • Ingestion: Rinse mouth, do not induce vomiting, and seek medical advice or attention immediately.
