| titleOfInvention | Mutual separation of rare earth elements using formation of gas phase complex |
| abstract | (57) [Summary] [Purpose] The separation of scandium, yttrium, and all rare earth elements from lanthanum to lutetium is performed by the dry method. [Constitution] A quartz or alumina tube is used as a reaction tube, and the tube is inserted into electric furnaces A and B capable of independently controlling the temperature. The electric furnace B is composed of heat-generating portions that are further divided, and is capable of forming a predetermined temperature gradient. The rare earth halide serving as a raw material and the metal halide serving as a complexing agent are introduced into the electric furnaces A and B to form a complex at a predetermined temperature, and then move to a temperature gradient portion together with a carrier gas, where each rare earth element is separated. It divides into and precipitates. |
