The analytical description of the specific electrical conductivity of the polythermic method in the series of fluorides of the s1-elements MF (M – Li, Na, K, Cs) is given by the function æ = f(Z), where Z is the ordinal number of the s1-element for temperatures higher than the melting temperature at 5, 10, 50, 75, 100, 150 and 200°. The values of æ melts RbF and FrF for these temperatures were calculated from the dependences obtained and the dependences æ = f(T) were described analytically. The literature data are compared with the values of æ(RbF) and calculated in this paper. A comparative method describes the dependence æT + n = f(æT + 5), where n = 50, 100, 150 and 200° above the melting points of MF. It is shown that the description of æ(MF) by the equations in this work has a lower value of the standard deviation than the equations given in the literature. The description of æ(MF) by two methods showed a satisfactory convergence of the results of the calculation of æ(RbF) and æ(FrF).
