Lead carbonate is the chemical compound PbCO3. It is prepared industrially from lead(II) acetate and carbon dioxide.
Old toxic Dutch Boy Paint, with basic lead carbonate and linseed oil
It occurs naturally as the mineral cerussite.[2]
Basic lead carbonates
There are a number of basic lead carbonates and related compounds, including:
- White lead, a basic lead carbonate, 2PbCO3·Pb(OH)2
- Shannonite, PbCO3·PbO
- 3PbCO3·Pb(OH)2·PbO[3]
- PbCO3·2PbO
- NaPb2(OH)(CO3)2
- Leadhillite, 2PbCO3·PbSO4·Pb(OH)2
Manufacturing
Lead carbonate is manufactured by passing carbon dioxide into a cold dilute solution of lead(II) acetate, or by shaking a suspension of a lead salt less soluble than the carbonate with ammonium carbonate at a low temperature to avoid formation of basic lead carbonate.
Regulations
The supply and use of this compound is restricted in Europe.[4]
