SYNTHESIS, ATTESTATION AND INVESTIGATION OF ELECTROCONDUCTIC CHARACTERISTICS BIMEVOX-BASED CERAMIC (Me = Ca, Cu, Mg, Ni)

Doped bismuth vanadates (Bi4V2–xMexO11–δ, Bi4V2-xMe0,5xMe'0,5xO11–δ, Bi4V2–xMe0,25xMe'0,25xMe''0,25xMe'''0.25xO11–δ, x = 0,2; Me,Me',Me'',Me'''=Mg,Ca,Cu,Ni) were obtained by solid-phase synthesis. The certification of the powdered samples was carried out by X-ray analysis. The parameters of the unit cell of the samples were determined. The transport characteristics were estimated by the method of impedance spectroscopy. The equivalent cell schemes for the different temperature regions were selected.
