Sulle applicazioni della termodinamica agli equilibri elettrodici
Some aspects of the application of phase rule to electrode equilibria are discussed. Examples are given.
Aspetti del comportamento elettrodico dell'alluminio in cloruri fusi
Anodic and cathodic overvoltages have been measured on Aluminium electrodes, both solid and liquid, in chloride melts by the method of galvanostatic pulse. The contribution of concentration polarization to apparent overvoltages has been stressed, while "true" reaction electrode overvoltages appeared to be negligible.
Studi sulle dispersioni di metalli in sali fusi
The new method for the dispersion of metals in molten salts has been successfully extended to fused metals (Ga and especially Al). Baths of chlorides (for Ga, Al) and fluorides (for Al) have been investigated in the range: 200° 1090° C. The dispersions are coarser than for solid metals and the settling rates higher. The particles are again positively charged and can be cataphoretically plated. The changes in the voltages of tensiometric cells, as a consequence of the formation of the dispersions,...
