(2) background technology:
At present, the method of the production metal or alloy powder (particle) of comparative maturity and extensive use on China's powder metallurgy industry is aerosolization, water atomization method, but metal or alloy powder (particle) size distribution that this method is prepared is inhomogeneous, each intergranular microstructure and physical and chemical performance have certain difference, use morely in traditional field such as surperficial anticorrosion with painting, but can not satisfy the application of high-tech sector.
(3) summary of the invention:
The purpose of this utility model is to design a kind of metal single-size generator, and it makes the problems referred to above be solved, and produces the metal or alloy powder of even particle size distribution, satisfies the needs that high-tech sector is used.
The technical solution of the utility model: a kind of metal single-size generator is characterized in that this device is made up of the container of quartz container, crucible, piezoelectric excitation generator, thermocouple, heater, protective gas feeding pipe, clapp oscillator, battery lead plate and interior dress cooling fluid; Said piezoelectric excitation generating apparatus is in crucible top oral area, the clapp oscillator that is connected with the piezoelectric excitation generator places bottom in the crucible, thermocouple and protective gas feeding pipe insert from top, crucible both sides respectively, heater places the crucible wall periphery, there is a micropore crucible bottom, nozzle is equipped with at the micropore place, battery lead plate places the outside below of crucible bottom nozzle, there is opening at battery lead plate and nozzle place relative crucible bottom parallel with crucible bottom, between crucible and battery lead plate potential difference is arranged, the container that cooling liquid is housed place the battery lead plate opening under; Said said apparatus places in the quartz container that vacuumizes.
The diameter of above-mentioned said crucible bottom nozzle is between 20-100 μ m.
