Plumbate
In chemistry, a plumbate often refers to compounds that can be viewed as derivatives of the anion.
Examples
Halides
Salts of,,, etc. are labeled as iodoplumbates. Lead perovskite semiconductors are often described as plumbates.Lead oxyanions
Plumbates are formed by the reaction of lead oxide,, with alkali. Plumbate salts contain either the hydrated hexahydroxoplumbate or plumbate anion, or the anhydrous anions or . For example, dissolving in a hot, concentrated aqueous solution of potassium hydroxide forms the potassium hexahydroxoplumbate salt. The anhydrous salts may be synthesized by heating metal oxides or hydroxides with.The most widely discussed plumbates are derivatives of barium metaplumbate. When doped with some bismuth in place of lead, the material exhibits superconductivity at 13 K. At the time of this discovery, oxides did not show such properties. The surprise associated with this work was eclipsed by the advent of the cuprate superconductors.
