Neue Verbindungen im Sillenittyp
Abstract
deNeue in der Sillenitstruktur kristallisierende Verbindungen wurden durch Reaktion bei 700–750°C in Korundtiegeln dargestellt: Bi12(V3/4Na1/4)O20, Bi12MnO20, Bi12(Mn1/2Ge1/2)O20, Bi12(Mn3/4Na1/4)O20, Bi12(Mn2/3M1/3)O20 mit M = Cu, Cd und Bi12(Mn1/2M1/2)O20 mit M = B, Al, Co. Gitterkonstanten wurden bestimmt und UV/VIS-Spektren gemessen.

enNew Sillenite-Type Compounds
New sillenite-type compounds (Bi12(V3/4Na1/4)O20, Bi12MnO20, Bi12(Mn1/2Ge1/2)O20, Bi12(Mn3/4Na1/4)O20, Bi12(Mn2/3M1/3)O20 with M = Cu, Cd and Bi12(Mn1/2M1/2)O20 with M = B, Al, Co) were synthesized at 700–750°C in corundum crucibles. Lattice constants have been determined and UV/VIS spectra have been recorded.
