(Central South University of Technology, Changsha 410083, China)
Abstract: The variations of chemical bonding characteristics in doped Sn0- base inert anodes with various dopants are studied using CNDO/2 quantum chemical calculations. A new model of conductivity is derived.which is checked with literature data and our experimental results. Proper dopants can be selected with the model to reduce the resistivity of said electrode effectively.
