STUDY OF POLYTYPIC PHASE RELATIONS AMONG COMPLEX INORGANIC STRUCTURES.
Abstract
The structure of 2PbO.Fe2O3, corresponding to the mineral hematophanite, and coexisting with plumboferrite in the PbO-Fe2O3 system, was determined to be a derivative of the perovskite structure. Relations with other structure types, e.g., diaboleite, cumengeite, pseudoboleite, boleite, and a ferroelectric mixed-layer series involving Bi2O2 and perovskite layers, are described. The superstructure of plumboferrite was redefined and its relation to magnetoplumbite clarified. Final results of the senaite structure determination are presented. Progress on the construction of a furnace for phase synthesis is reviewed. (Author)
