| Abstract: | The phase relation and conductivity for the binary Na_2Mo_(0.1)S_(0.9)O_4(α) and no-earth sulphate systems has been researched using XRD, DTA and electrical measurment technique. It has been found that the electrical conductivity can reach the order of 10~(-3) in the system doped with 8m/o CaSO_4at 280℃, which is similar to the effect of doping earth sulphates, but there is still phase transition in the binary system. The reason why the electrical conductivity can be considerably increased and the phase transition exists after doped with aliovalent ions has also been discussed. |
