CAS 1309-60-0

Lead dioxide

Description:

Lead dioxide, with the CAS number 1309-60-0, is an inorganic compound characterized by its dark brown to black appearance and its chemical formula PbO2. It is a strong oxidizing agent and is primarily used in lead-acid batteries, where it serves as the positive plate material. Lead dioxide is insoluble in water but can dissolve in strong acids, forming lead(II) ions and other lead compounds. The compound exhibits a tetragonal crystal structure and has a high melting point, making it stable under various conditions. Its oxidation state of +4 in lead dioxide contributes to its reactivity, particularly in redox reactions. Due to its toxic nature, lead dioxide poses health and environmental risks, necessitating careful handling and disposal. Additionally, it can participate in various chemical reactions, including the oxidation of organic compounds and the synthesis of other lead-based materials. Overall, lead dioxide is significant in industrial applications, particularly in energy storage and electrochemistry.

Lead Dioxide

CAS: 1309-60-0

Lead dioxide is a compound with the chemical formula PbO. It is used in wastewater treatment and as a pigment in paints and enamels. Lead dioxide is insoluble in water and has a high surface tension, which allows it to be used as an anti-fouling agent by coating the inside of sewage pipes. The solubility of lead dioxide decreases with an increase in temperature, so it precipitates at higher temperatures due to its low solubility. Lead dioxide is thermodynamically stable up to about 400 degrees Celsius. It reacts with water through transfer reactions, where the lead is oxidized to PbO2+ ions. Lead dioxide has a hydrophobic effect, which may be due to its ability to form clathrates with organic molecules. It can also react with other substances such as CO2, HCl and NH3 to form lead salts. Lead dioxide can also be used as an optical sensor or thermometer because of its dependence on temperature for phase transition
