概要

We tried several experiments and consideration on the system of GaO-SiO_2-Al_2O_3. (a) It was found that molten slags were ionic by the measurements of voltage-current relations. (b) Molten slags were decomposed by D. C. source in some conditions and after that they were analysed by the new improved polarograph with Hg-dropping cathode, and ionic behaviors during electrolysis were examined. So it was presumed that Al^<+++>, AlO_3^<---> were more sensitive for electrolysis than Ca^<++> and were playing larger parts for the electric conductivity. (c) Movable oxygen ions, probably existing in molten slags, jump from positive ions to negative complex ions by electric conductance belonging to Grotthuss type, and they determine the acidic or basic strength of the slags.
