Lead polonideLead polonide is the polonide of lead, with the chemical formula of. It occurs naturally, as lead is produced in the alpha decay of polonium.PreparationLead polonide can be formed by reacting polonium vapour and lead under a vacuum.PropertiesLead polonide has a sodium chloride structure, which is the same as lead telluride. It has a cubic crystal structure, with the space group Fmm, with lattice constant a = 6.59 Å.
