Title:
APPARATUS FOR PREPARING HYPER-FINE PARTICLE
Document Type and Number:
Japanese Patent JP3803757
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To propose an apparatus for advantageously manufacturing hyper-fine particles of a uniform grain size distribution by advantageously preventing the aggregation and remelting caused by a force evaporation method.
SOLUTION: The apparatus is equipped with a hyper-fine particle generating chamber 1 and a hyper-fine particle catching chamber 2 connected to the hyper-fine particle generating chamber 1, is arranged with a material placing table 4 and an electrode 5 for discharge in proximity to each other, is provided with an introducing port 7 for gas to be brought into reaction by the arc discharge within the hyper-fine particle generating chamber 1 and conveys the hyper-fine particles generated by the evaporation of the material placed on the material placing table 4 by a gaseous stream. The hyper-fine particle generating chamber 1 has an approximately semi-cylindrical shape and its one end continuing into the hyper-fine particle catching chamber 2 is shaped to consist of a semi-conical shape.
