WebThe electrolytic process is limited to the rare earth metals, which melt below 1.050 ° C (1.922 ° F), because those that melt much higher react with the electrolysis cell and the electrodes. As a result, the electrolytic cell and the electrodes must be exchanged frequently, and the generated rare earth metals are highly contaminated.
