[ Structure ]
There are two crystal forms of lead monoxide, α-PbO is red crystal, tetragonal crystal system, density 9.35g/cm3. β-PbO is a yellow crystal, orthorhombic crystal system, with a density of 9.64g/cm3. β-PbO can be boiled in water to get α-PbO, and β-PbO can also get α-PbO by grinding β-PbO at room temperature; α-PbO is converted into β-PbO at 475~583℃.
