Descrição

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
