Zusammenfassung: 
Potassium and lead substituted single and polycrystalline material was examined by X-ray diffraction, X-ray topography, nonresonant microwave absorption, UPS and XPS. A covalent model instead of an ionic one is proposed. We find no evidence for a mixed valency of Bi. The valency of the Bi atoms at the unequivalent sites is close to 3. No density of states at the Fermi level has been detected.
