PROBLEM TO BE SOLVED: To provide a method for introducing other components into a crystal, capable of rapidly and efficiently introducing the other components of an arbitrary amt. into this crystal. SOLUTION: The crystal and a material contg. the components different from the constituting components of the crystal are charged into a vacuum stirrer and are stirred and mixed under a reduced pressure, for example, -700 to -750mmHg, by which the other components are dispersed into the crystal. The crystal of common salt and mineral component-contg. materials are charged into the vacuum stirrer and are stirred and mixed under -700 to -750mmHg, by which the mineral components are introduced into the crystal of the common salt. |
