Purification of samarium metal by sublimation and purification by vaporization from a low-melting metal flux are compared at the same temperature. Vaporization is more effective for removing impurities such as magnesium, calcium, and manganese. Recovery of samarium, however, is more rapid by sublimation because of its constant rate of distillation.
