The two electrodes are separated by a wire gauge partition to avoid the mixing of sodium and chlorine so formed. As sodium chloride melts at a very high temperature of 1085 K, a mixture containing sodium chloride, potassium chloride and potassium fluoride (N a C l + K C l + K F) is employed. This mixture melts at about (850 − 875) K.
