Product Description
Lead (II) carbonate basic is a white heavy powder with a hexagonal crystal structure. It is insoluble in water and ethanol but dissolves in strong acids such as acetic acid and nitric acid. The compound is stable under normal temperature and pressure. When heated to 220℃ for 4 hours, about 9% of the carbon dioxide is released, and 95% is converted into PbCO3⋅PbOPbCO3⋅PbO. At 400℃, it decomposes completely into lead oxide with the release of carbon dioxide. Upon contact with hydrogen sulfide, it gradually darkens, forming 4PbCO3⋅PbS⋅Pb(OH)24PbCO3⋅PbS⋅Pb(OH)2.
