PROBLEM TO BE SOLVED: To provide a composite obtained by combining a negative ion-ceramic and germanium, which preferably synergistically enhances the working-effect of the both materials. SOLUTION: The germanium and negative ion-ceramic composite is obtained by having fine particles of germanium carried on an open-cell porous ceramic body and firing it. COPYRIGHT: (C)2007,JPO&INPIT
