Title:
REACTION DEVICE AND METHOD FOR PRODUCING REDUCTION PRODUCT OF OXIDE SAMPLE
Document Type and Number:
WIPO Patent Application WO/2023/149293
Kind Code:
A1
Abstract:
The present disclosure addresses the problem of providing a reaction device that can increase the refinement amount of a reduction product, that makes it easy to control the sample temperature, and that facilitates mass production. The present disclosure also addresses the problem of providing a method by which a reduction product of an oxide sample can be efficiently obtained using said reaction device. A reaction device 100 according to the present disclosure comprises at least: a reaction chamber 15 for accommodating a plasma source 13, such as a metal, and an oxide sample 14 that is to be reduced and is distinct from the plasma source; an exhaust pump 12 that discharges gas from inside the reaction chamber; one or more cavity resonators; and a heating mechanism for heating the oxide sample. At least one of the cavity resonators has a shape that forms a magnetic field intensity distribution at the center of the cavity resonator. The reaction device includes, as a cavity resonator, a first cavity resonator 8 for irradiating all or part of the plasma source with microwaves and generating plasma from the plasma source.
