Oa. Bunina et al., The phases of tetragonal tungsten bronze in the ternary oxide system Ba2Li2Nb10O30-Pb2Li2Nb10O30-Sr2Li2Nb10O30, FERROELECTR, 247(1-3), 2000, pp. 67-73
Polycrystalline solid solutions of the ternary oxide system (Ba,Pb,Sr)(4)Li
2Nb10O30 were investigated by means of roentgenographic and dielectric meth
ods. As a result, a phase diagram of the system has been constructed. Sever
al different tetragonal tungsten bronze (TTB) phases have been found and th
eir boundaries located.
