Plumbic oxide, also known as lead(IV) oxide or lead dioxide, is a chemical compound with the formula PbO2. It appears as a dark brown or black solid and is primarily used in various industrial applications, including the production of lead-acid batteries and as a pigment in ceramics and glass. This compound is notable for its strong oxidizing properties, making it useful in chemical reactions and processes. However, due to the toxicity of lead, safety precautions are essential when handling plumbic oxide to prevent health risks associated with lead exposure.
