In aqueous solution, the chlorides of lanthanum, cerium and praseodymium cristallize as heptahydrates, those of the other rare earth elements as hexahydrates. Therefore, a miscibility gap exists in the solid phases in all systems comprising the two types of chlorides. Five ternary systems and a quaternary one with this behaviour have been studied.
