3. Product Applications
Litharge, or lead(II) oxide (PbO), has several applications in various industries. Here are some common uses of litharge:
Lead-Acid Batteries: Litharge is a crucial component in the production of lead-acid batteries. It is used in the positive electrode (cathode) to facilitate the conversion of electrical energy into chemical energy during the battery's operation.
Glass and Ceramics: Litharge acts as a fluxing agent and colorant in the production of glass and ceramics. It helps lower the melting point of the materials, improves their workability, and enhances the transparency and brilliance of the final products.
Pigments: Litharge is used as a pigment in paints, coatings, and ceramics. It provides a bright yellow or reddish-yellow color to these materials.
Fireworks: Litharge can be employed in the pyrotechnics industry to produce yellow or red color effects in fireworks.
Rubber Industry: Litharge is used in the rubber industry as an accelerator and curing agent in the production of certain types of rubber, such as neoprene.
