Description
Technical field
New material power production engineering device technique field is the utility model is related to, is specifically a kind of sub-micron and Nano metal powder
The production equipment of body.
Background technology
The production technology of nano material is the key of nano material technology development, research and application, at present nano material
Up to tens kinds of technology of preparing.Nano metal powder is as a kind of widely applied material of nano material, particularly in high-quality
In the preparation of nano metal powder, realize that industrialization best method has vaporize-condensation law and high-temperature hydrogen reduction method.Evaporation-condensation

Rice and nano metal powder the best way.
1984, Gleiter was prepared for extra-fine nickel powder using vaporize-condensation law first, and this method is to utilize electric arc, high frequency
The high temperature heat source such as electric field or plasma by raw metal in high vacuum or low-pressure inert gas, heating and gasifying or distillation,
Then rapid condensation is into superfine powder, and this method can prepare various submicron particles, and feature is any surface finish, size tunable,
Good sphericity.At subsequent more than 30 years, various countries researcher was researched and developed once again on the Research foundation of Gleiter, passes through equipment
Upgrading, the change of mode of heating, the further investigation of theoretical foundation, the technology of vaporize-condensation law obtained significant progress.
Different according to mode of heating, vaporize-condensation law particularly may be divided into electrical resistance heating, induction heating method, laser
Heating, electron beam heating and plasma heating method etc., the brief of its different heating method are compared, as shown in table 1.
The comparison sheet of 1 vaporize-condensation law different heating mode of table
| Mode of heating | Atmosphere | System pressure (Pa) | Yield | Equipment requirement |
| Resistance heating | Inert gas | 133~13332 | It is low | It is low |
| High-frequency induction heating | Inert gas | 133~6500 | It is low | It is low |
| Electron beam heats | Inert gas | 133 | It is low | It is high |
| Laser beam heats | Inert gas | 1300~14000 | It is low | It is high |
| Plasma heating | Inert gas | 26000~100000 | It is medium | It is low |
