DEVICE AND METHOD FOR MANUFACTURING FINE POWDER BY USING ROTARY CRUCIBLE

摘要

It is possible to provide a method and device for manufacturing powder of fine particles having a small particle diameter distribution width, i.e., similar particle diameters, with a high productivity. A molten raw material A is introduced to a bottom surface in the vicinity of the rotation axis center of a rotary vessel having a heated cylindrical crucible (10) arranged in a chamber. The molten raw material is subjected to a centrifugal force so as to be pushed against the inner wall of the crucible and injected to fly into the chamber containing an atmospheric gas such as argon, helium, nitrogen, and air by a centrifugal force from an opening of the crucible, so as to manufacture an ultra-fine powder B having similar particle sizes.
