Solid solutions on the base of bismuth vanadate: Preparation, structure, phase transitions, dielectric and transport properties
چکیده انگلیسی

Ceramic solid solutions (Bi1-yLay)4(V1-xMex)2O11-y with x, y < 0.2, Me–Zr, Ga, Fe, Cu, have been prepared by the solid state reaction method. Crystal structure parameters, phase transitions, dielectric and transport properties of ceramic samples have been studied. Concentration and temperature stability regions of monoclinic α-, orthorhombic β- and tetragonal γ- or γ’- polymorph modifications have been determined.Annealing of samples, containing large amount of Cu and/or La dopants, at 973 K in the reducing atmosphere resulted in their decomposition, though compositions containing low content of La, Ga or Zr dopants, remained pretty stable.
