Product Description

Product Description

Cobalt Sulfate
Basic Information

• Chemical Formula:
  • Anhydrous: CoSO4
  • Heptahydrate (most common): CoSO4.7H2O
• CAS Number:
  • Anhydrous: 10124-43-3
  • Heptahydrate: 10026-24-1 (Note: CAS numbers are often shared, but distinctions depend on the specific form)
• Molar Mass:

Physical Properties

Property	Anhydrous Cobalt Sulfate	Heptahydrate Cobalt Sulfate
Appearance	Blue powder or crystals	Red to purplish-red monoclinic crystals
Solubility	Highly soluble in water (≈36.2 g/100 mL at 25ºC); soluble in methanol, slightly soluble in ethanol	Soluble in water (aqueous solution is acidic)
Melting Point	Decomposes at 986ºC	Loses water of crystallization at 98ºC
Density	3.05 g/cm³	1.949 g/cm³
Hygroscopicity	Strongly hygroscopic, prone to deliquescence	Stable at room temperature, loses water at high temperatures

Chemical Properties

1. Thermal Decomposition:
   • Decomposes at high temperatures into cobalt oxide (CoO), sulfur dioxide (SO2), and sulfur trioxide (SO3):2CoSO4High TemperatureCoO+SO2↑+SO3↑
2. Hydration and Dehydration:
   • The heptahydrate loses 4 water molecules at 55-65ºC to form the trihydrate (CoSO4·3H2O) and becomes anhydrous above 100ºC.
3. Reactivity:
   • Aqueous solutions are acidic and react with alkalis to form cobalt hydroxide precipitate:CoSO4+2NaOH→Co(OH)2↓+Na2SO4
   • Reacts with carbonates to form cobalt carbonate:CoSO4+Na2CO3→CoCO3↓+Na2SO4

Main Applications

1. Battery Industry:
   • Serves as a cobalt source for lithium-ion battery cathode materials (e.g., lithium cobalt oxide, ternary materials), critical for new energy vehicles and energy storage.
2. Electroplating Industry:
   • Used in electroplating baths for cobalt coatings to enhance surface hardness and corrosion resistance.
3. Pigments and Ceramics:
   • Produces cobalt blue pigment for glazes and glass coloring.
4. Catalysts:
   • Acts as a catalyst or catalyst support in organic synthesis and petrochemicals.
5. Agriculture and Medicine:
   • Micro-nutrient fertilizers for plant cobalt supplementation; used in pharmaceuticals to synthesize vitamin B12 derivatives.
6. Others:
   • Production of cobalt salts (e.g., cobalt carbonate, cobalt oxalate) and magnetic materials.

Safety and Hazards
Hazard Summary

• Health Risks:
  • Inhalation or ingestion may cause poisoning, leading to nausea, vomiting, and diarrhea; long-term exposure may damage the liver and kidneys.
  • Dust irritates the eyes and respiratory tract; skin contact may cause allergies.
• Environmental Risks:
  • Cobalt is a heavy metal toxic to aquatic life, potentially bioaccumulative in food chains.
• Fire and Explosion:
  • Non-combustible, but high-temperature decomposition releases toxic sulfur oxides.

Safety Precautions

• Personal Protection:
  • Wear dust masks, protective goggles, and acid-resistant gloves; avoid direct skin and mucous membrane contact.
• Storage and Transportation:
  • Store in sealed containers in cool, dry places, away from oxidizers and alkalis; prevent moisture and impact during transport.
• Emergency Response:
  • For spills, cover with inert materials (e.g., sand) and collect for professional disposal; flush skin with water, and seek medical help immediately if ingested.
