Abstract: Al-Ca master alloy was prepared in a labora- tory electrolysis cell.The operating parameters used were:temperature range 680-720℃,cathodic cur- rent density 0.76-1.10 A/cm~2,bath composition in wt-% 75-85 CaCl_2+2-5 KCl+2-5 CaF_2.Un- der optimal conditions the current efficiency reached 70-80% and the Ca-content 10-14 wt-%.

Key words: AI-Ca master alloy, electrolysis
