Litharge, with the chemical formula PbO, is an inorganic compound formed by one lead atom and one oxygen atom. It generally appears as a fine yellow powder. This compound has a specific crystalline structure, which gives it unique physical and chemical properties, making it ideal for various industrial applications.
Litharge is produced through the controlled oxidation of metallic lead, a process mastered by chemical engineering experts that ensures the production of a uniform, stable material with reproducible characteristics. Its purity and reactivity make it a key input for sectors such as mining, ceramics, special glasses, pigments, and battery manufacturing.
