Lead(II) carbonate is the chemical compound PbCO3. It is prepared industrially from lead(II) acetate and carbon dioxide.
It occurs naturally as the mineral cerussite.[2]
Carbonate[edit]

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
- Abellaite, NaPb2(OH)(CO3)2
- Leadhillite, 2PbCO3·PbSO4·Pb(OH)2
Manufacturing[edit]
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 more soluble than the carbonate with ammonium carbonate at a low temperature to avoid formation of basic lead carbonate.
- Pb(CH3COO)2 + (NH4)2CO3 → PbCO3 + 2 NH4(CH3COO)
Regulations[edit]
The supply and use of this compound is restricted in Europe.[4][not in citation given]
