STUDY OF POLYTYPIC PHASE RELATIONS AMONG COMPLEX INORGANIC STRUCTURES.
Abstract
Senaite was found to be closely related to magnetoplumbite and the hexagonal-ferrites. Three dimensional intensity data were collected, analyzed and used for the computation of the Patterson function P (u,v,w). Analysis of the implication function I3 (u,v,o) together with chemical analyses shows that it has the chemical formula Pb (Ti,Fe,Mn,Mg)24O38. Davidite, which has no cation in the closest-packed framework is shown to be isotypic with senaite and to have the formula (Ti,Fe)21O39. Thus senaite is a compositional and structural link between the Ba-ferrite type phases and other closest-packed oxide phases. Data are also presented on nigerite, plumbo-ferrite and CoGeO3. (Author)
