Industrial Uses

1. Energy

  • Active Material in Lead-Acid Batteries: Lead oxide is a critical component in the production of lead-acid battery plates. PbO is used to form the paste applied to battery plates, which undergoes chemical conversion during charge/discharge cycles. It plays a central role in electrochemical energy storage.

2. Paints, Coatings & Adhesives

  • Additive in Leaded Glass and Glazes: Lead oxide improves the optical properties and durability of specialty glass (e.g., crystal glassware, radiation shielding glass). It increases refractive index, brilliance, and chemical resistance. In ceramics, it is used in glazes and enamels to enhance smoothness, shine, and stability.
  • Red Pigment (Red Lead – Pb₃O₄) : Red Lead is used as a corrosion-resistant primer pigment in protective paints for steel structures, ships, and bridges. It provides long-lasting rust protection. Due to its toxicity, its use is regulated and declining.

3. Polymers & Resins

  • Heat Stabilizer and Vulcanization Agent: Lead oxide is used in PVC heat stabilizers and in rubber compounding to improve thermal stability and aging resistance. It also plays a role in accelerating vulcanization.

4. Lubricants & Automobiles

  • Additive in High-Pressure Lubricants: Lead oxide is used in extreme pressure (EP) greases and high-temperature lubricants, especially in industrial and military applications. It enhances load-carrying capacity and reduces wear under heavy mechanical stress.
