METHOD OF FORMING METAL PLATING FILM ON SURFACE OF FERRITE GRANULATED POWDER, FERRITE GRANULATED POWDER HAVING METAL PLATING FILM ON SURFACE, AND TEMPERATURE SWITCH ELEMENT PRODUCED USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method wherein a metal plating film is formed on the surface of ferrite granulated powder produced in such a manner that, after granulation with an organic binder, heat treatment is performed so as to thermally decompose and remove the binder by wet plating treatment, to provide ferrite granulated powder having a metal plating film on the surface, and to provide a temperature switch element produced by using the same.;SOLUTION: Granulated powder is subjected, in a first stage, to an electroless plating treatment after a palladium surface activation treatment is applied, and is further subjected, in a secondary stage, to an electroless plating treatment after the palladium surface activation treatment is applied.;COPYRIGHT: (C)2005,JPO&NCIPI
