Lead 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]

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]
