Electroconductive and dielectric properties of composites based on bismuth vanadate

Ceramic composites (100 -n)Bi4V2O11-x- nCe0.9 with n = 0 ÷ 25 wt% were prepared and studied by the X-ray diffraction, dielectric spectroscopy, and impedance methods. Slight increase in the unit cell volume accompanied by monotonous decrease in temperatures and broadening of the α-β and γ-f phase transitions with increasing fluorite content was observed in the composites studied. Increase in melting temperatures of composites with n ≥ 10 with the retention of their high ionic conductivity was also proved.
