SUBLIMATION REFINING RECOVERY METHOD AND SUBLIMATION REFINING RECOVERY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a sublimation refining recovery device capable of efficiently recovering a treatment object substance in sublimation refining, without executing complicated work, in the present invention.;SOLUTION: The sublimation refining is executed by providing a filter 8 constituted of a raw material having heat conductivity of the room temperature (20°C) and atmospheric pressure (1atm) of 1-500 W/(m K), in a temperature area for coagulating the treatment object substance in a sublimation refining pipe (an outer pipe) 4a and a sublimation refining pipe (an inner pipe) 4b heated so as to have a temperature gradient, by carrying the treatment object substance 9 sublimated in the sublimation refining pipe (the outer pipe) 4a and the sublimation refining pipe (the inner pipe) 4b of decompressing the inside by inert gas 10.;COPYRIGHT: (C)2014,JPO&INPIT
