Ceramic composites (100 - n)Bi4V2O11-z-nCe0.9Gd0.1O1.9 with n=0÷25 wt% were prepared and studied by the 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 β-γ 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.
