Paper Abstract

Crystals of solid solutions of K0.82Tl0.18TiOPO4, K0.59Tl0.41TiOPO4, Rb0.77Tl0.23TiOPO4, KGe0.04Ti0.96OPO4, KGe0.06Ti0.94OPO4, KGe0.18Ti0.82OPO4, TlTiOPO4 and KGeOPO4 were obtained by crystallization from nonstoichiometric melts. These crystals belong to the ferroelectric family which possesses superionic conductivity of the KTiOPO4-type. Their crystal structures were established and electrophysical characteristics were studied. The crystals are orthorhombic, sp.gr. Pna21. In these crystals, as compared to KTiOPO4 crystals, TiO6-octahedra have a more regular structure, that is one of the reasons of the differences in the nonlinear optical characteristics.
