Product Details
Basic lead(II) carbonate is a dense white powder with a hexagonal crystal structure. It is insoluble in water and ethanol, yet readily soluble in strong acids including acetic acid and nitric acid.
The compound remains stable under standard temperature and pressure conditions. When heated at 220 ℃ for four hours, approximately 9% of its carbon dioxide content decomposes, converting 95% of the substance into PbCO3⋅PbO. At 400 ℃，it undergoes further decomposition into lead oxide with carbon dioxide released. When exposed to hydrogen sulfide, it gradually darkens to black, forming the product 4PbCO3⋅PbS⋅Pb(OH)2.
