[f. L. plumb-um lead + -ic. Cf. F. plombique.]
Of or pertaining to lead. a. Chem. Combined with lead; applied to compounds in which lead has its higher valency (quadrivalent), as plumbic acid, dioxide of lead, PbO2. Formerly also applied by some writers to compounds of bivalent lead (cf. plumbous a. 2).
