Title:

MANUFACTURING METHOD FOR MAGNETIC FREEZING MODULE

Document Type and Number:

WIPO Patent Application WO/2016/140350

Kind Code:

A1

Abstract:

　This manufacturing method for magnetic freezing module comprises: a step (1) in which a mixed powder A is prepared, said mixed powder containing an La (Fe, Si)13 alloy powder having a NaZn13 crystalline structure as the main phase thereof, a powder M comprising a metal and or alloy thereof, the metal having a melting point not exceeding 1090°C, and an organic binder as necessary; a step (2) in which a mixed powder A is heat-treated in the vicinity of the melting point of the powder M in a reducing atmosphere, to obtain a sintered compact B, and a step (3) in which the sintered compact B is hydrogenated in a hydrogen-containing atmosphere.
