Product Description

Product Description

Basic Information

• Product Name: Lead(II) sulfate, lead sulfate
• Chemical Formula: PbSO4
• Molecular Weight: 303.26 g/mol
• CAS Number: 7446-14-2
• EINECS Number: 231-198-9

Physical and Chemical Properties

• Appearance: White crystalline powder; may appear slightly yellowish due to impurities.
• Melting Point: Decomposes at high temperatures (approx. 1000°C) without melting.
• Density: 6.2 g/cm³ (solid).
• Solubility:
  • Sparingly soluble in water (0.0042 g/100 mL at 20°C).
  • Soluble in concentrated sulfuric acid, ammonium acetate, and solutions of caustic alkalis (due to complex formation).
• Stability: Stable under normal conditions; non-combustible but decomposes to release toxic lead fumes when heated strongly.
• Crystal Structure: Orthorhombic crystal system.

Main Applications

1. Lead-Acid Batteries:
   • Critical component in the electrodes of lead-acid batteries (e.g., car batteries). During discharge, both the anode (lead) and cathode (lead dioxide) react with sulfuric acid to form PbSO4, which is converted back to lead and lead dioxide during charging.
2. Pigments and Coatings:
   • Historically used as a white pigment in paints, but its use has declined due to lead toxicity. It may still be found in some specialized coatings.
3. Ceramics and Glass:
   • Added to ceramic glazes to improve durability and luster; used in leaded glass to enhance optical properties (e.g., refractive index).
4. Industrial Catalyst:
   • Occasionally used as a catalyst in certain organic reactions, though its toxicity limits its application.
5. Laboratory Reagent:
   • Used in analytical chemistry for the detection and quantification of lead or sulfate ions.

Packaging and Storage

• Packaging: Sealed in plastic or fiber drums, or hermetically sealed containers.
• Storage Conditions: Store in a dry, well-ventilated area, away from moisture and strong acids. Keep containers tightly closed to prevent contamination.

Safety and Toxicity

• Hazards:
  • Toxic if ingested, inhaled, or absorbed through the skin. Lead exposure can cause neurological, renal, and hematological damage, especially in children.
  • Classified as a possible human carcinogen (IARC Group 2B) due to lead content.
  • Environmental hazard: Toxic to aquatic life, with long-term effects.
• Handling Precautions:
  • Wear protective gloves, masks, and goggles to avoid contact and inhalation.
  • Work in a fume hood when generating dust.
  • Dispose of waste according to hazardous material regulations; do not contaminate water sources.
• Regulatory Classification:
  • Listed as a hazardous substance under REACH, OSHA, and other international regulations.
