Description

Lead Monoxide, also known as litharge, is a vital inorganic compound with the CAS registry number 1317-36-8. This versatile material serves as a fundamental precursor and performance additive in numerous industrial processes. It is essential for manufacturers in sectors such as glass and ceramics, battery production, and the synthesis of other lead-based compounds, where its specific chemical properties are leveraged to enhance product characteristics and process efficiency.

Application

• Glass and Ceramics Manufacturing: A key component in lead crystal, optical glass, and ceramic glazes, where it lowers melting temperature and increases refractive index and brilliance.
• Lead-Acid Battery Production: Used in the formation of battery plates and as a raw material in the manufacture of leady oxide for the battery paste.
• Chemical Synthesis: Acts as a crucial starting material for producing other lead compounds like lead stabilizers for PVC, lead pigments (e.g., chrome yellow, red lead), and lead salts.
• Pigments and Drying Agents: Employed in the formulation of certain corrosion-resistant paints and as a drier in oil-based paints and varnishes.
• Rubber and Plastics: Functions as an activator in rubber vulcanization and as a heat stabilizer in specific plastic formulations.
• Radiation Shielding: Incorporated into specialized glass, ceramics, and polymers for X-ray and γ-ray shielding applications.
