MAGNESIUM REFINING DEVICE, AND MAGNESIUM REFINING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/109362
Kind Code:
A1
Abstract:
A magnesium refining device provided with: a housing vessel which houses a sample that includes a magnesium compound; and a light focusing device which focuses sunlight so as to irradiate the housing vessel therewith, and heats the interior of the housing vessel to a prescribed temperature. The housing vessel has a reaction unit which causes a magnesium vapour to be produced from the sample by a thermal reduction reaction as a result of being heated to the prescribed temperature by the light focusing device. The light focusing device comprises a Cassegrain optical system which has a first mirror surface comprising a concave mirror, and a second mirror surface comprising a convex mirror. Reflected light, which is sunlight reflected by the first mirror surface, is guided to the second mirror surface, and the reflected light is focused onto the surface of the sample in the housing vessel by being reflected by the second mirror surface.
