Abstract: An electrolysis technique for co-deposition of Ca2+and Na+at the liquid lead cathode was put forward. The experiment was carried out at an electrolysis temperature below 650℃and had a current efficiency of 98%, which are respectively 100~300℃lower and 15%~30% higher than those reported both at home and abroad.
Key words: Pb-Ca-Na master alloy molten chloride salt electrolysis preparation
