| Abstract: | A definite NaBiF4 phase and a solid solution Na1?xBixF1+2x (0,60 ? x ? 0,70) of fluorite derived type have been obtained at 430°C in the NaF - BiF3 system. Investigation of the electrical properties of these materials shows that Na0,40 Bi0,60 F2,20 is the best anionic conductor of the system, with a conductivity of about 10?3 Ω?1 cm?1 and 100°C and an activation energy of 0,46 e v. The results are discussed in comparison with those previously obtained for the KF - BiF3 and RbF - BiF3 systems. |
