- Аннотация: The structure of a crystal frown by crystallization from flux in the K2O-TiO2-Nb2O5-P2O5 system was studied by the methods X-ray diffraction analysis at room temperature. The crystals of the composition K2.47Nb2.85Ti1.15P2.5O17 are monoclinic, a = 13.7564(7) Angstrom, b = 6.4075(3) Angstrom, c = 16.9383(7) Angstrom, beta = 83.15(1)degrees, sp. gr. P2/n. The structure was solved by the direct method using the SHELXS86 program package and refilled by the JANA96 program. The crystal structure consists of a three-dimensional framework of sharing-vertices (Nb,Ti)O-6-octahedra and the PO4-tetrahedra and two types of channels along the diagonal [101] direction, which are statistically occupied by potassium cations providing ionic transport in the compound.
