Lead(II) carbonate is the chemical compound PbCO3. It is prepared industrially from lead(II) acetate and carbon dioxide.

Contents

It occurs naturally as the mineral cerussite.

Carbonate

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
  • PbCO3·2PbO
  • Abellaite, NaPb2(OH)(CO3)2
  • Leadhillite, 2PbCO3·PbSO4·Pb(OH)2

    • Manufacturing

    Lead carbonate Lead Carbonate Suppliers Manufacturers amp Traders in India

    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.

    Pb(CH3COO)2 + (NH4)2CO3 → PbCO3 + 2 NH4(CH3COO)

    Regulations

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