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]

There are a number of basic lead carbonates and related compounds, including:

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 less soluble than the carbonate with ammonium carbonate at a low temperature to avoid formation of basic lead carbonate.

Regulations[edit]

The supply and use of this compound is restricted in Europe.[4]
