Document Type and Number:
WIPO Patent Application WO/2013/009066
Kind Code:
A2
Abstract:
Provided is a vacuum heat treatment apparatus having a structure which is able to improve the recovery rate of synthesized powder by optimizing a shape of a reaction container, and prevent a scattering phenomenon of the synthesized power within the reaction container, and at the same time to enhance a recovery amount of the powder in such a manner that reaction gas has vortex flow thanks to a groove of a lower part of a cover unit and is discharged to the outside through an exhaust port formed on an upper part of a crucible.
