lead(II) oxide
Quick Summary
Lead(II) oxide (PbO) is a chemical compound that exists in two mineral forms: litharge and massicot. Litharge is typically red or reddish-yellow, while massicot is yellow. This compound is manufactured by oxidizing metallic lead and is crucial in various industrial applications.123
A primary use of litharge is in the production of storage batteries. It is also vital in manufacturing glass, including components for television and computer screens, due to lead's ability to block harmful radiation. Additionally, lead(II) oxide is used in enamels, frits for glass production, and to enhance the strength and brilliance of fine crystal glassware. It also plays a role in creating pigments, acts as an accelerator in rubber production, and serves as a catalyst in oil refining.4
Other lead oxides include lead dioxide (PbO2), an oxidizing agent used in dyes and matches, and red lead (Pb3O4), used in paints and batteries. Lead compounds are known to be toxic and can accumulate in the body, leading to health issues.453
