Filling electrode mass based on zirconium dioxide and phosphate binders

Technique of a new filling electrode using introduction of filling mass into the composition on the basis of ZrO2-CaO, orthophosphoric acid and additions of indium oxide is developed. Conductivity of the filling mass of the above composition increases by the factor of 10, at that, mechanical strength of filling electrodes on the basis of ZrO2-CaO + 10% In2O3 were tested in U-02 and U-25 channels. The electrodes possess a higher erosion stability and better current characteristics than the filling mass on the basis of ZrO2-CaO
