Just because its toxic does not mean it's particularly surprising that it has practical uses (cyanide is used for gold extraction, arsenic is a semiconductor etc) . Also, it says "several practical uses", but only one practical use is explained in the article, so removed that for consistency. |

==Structure== |
|||
⚫ | |||
Like all metal carbonates, lead(II) carbonate adopts a dense, highly crosslinked structure consisting of intact {{chem2|CO3(2-)}} and metal cation sites. As verified by [[X-ray crystallography]], the Pb(II) centers are seven-coordinate, being surrounded by multiple carbonate ligands. The carbonate centers are bonded bidentate to a single Pb and bridge to five other Pb sites.<ref>{{cite journal|doi=10.1524/zkri.1974.139.3-5.215|title=Verfeinerung der Kristallstruktur von Cerussit, PbCO3|journal=Zeitschrift für Kristallographie|volume=139|issue=3–5|pages=215–222|year=1974|last1=Sahl|first1=Kurt|bibcode=1974ZK....139..215S}}</ref> |

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

[[File:EntryWithCollCode6178Hepta.png|thumb|left|Pb site in {{chem2|PbCO3}}, highlighting seven-coordination and the presence of one [[bidentate ligand|bidentate]] carbonate ligand for each Pb center.]] |

==Production and use== |
|||
⚫ | |||
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.<ref name=Ullmann>{{Ullmann|first=Dodd S.|last=Carr|year=2005|title=Lead Compounds|doi=10.1002/14356007.a15_249}}</ref> |

Lead carbonate is used as a catalyst to polymerize formaldehyde to [[poly(oxymethylene)]]. It improves the bonding of [[chloroprene]] to wire.<ref name=Ullmann/> |
