| titleOfInvention | Apparatus for producing ultrafine particle |
| abstract | PURPOSE: To efficiently produce ultrafine particles by disposing the 1st electrode for arc discharge to face a base material and disposing the 2nd electrode for arc discharge at the angle different from the angle between said electrode and the base material at the time of producing ultrafine particles by an arc heat. n CONSTITUTION: The inside of a chamber 1 is evacuated and a prescribed gas is sealed therein to about 1MPa. Electric current is supplied from an electrode 10 to generate a gaseous tungsten arc from the 1st electrode 4 for arc discharged and a gaseous plasma arc from the 2nd electrode 5 for arc discharge so that the arc 6 having the prescribed shape is formed. The gaseous plasma arc from the 2nd electrode 5 has no deflection of the arc by electromagnetic force as the current density is large. The base material 3 is thus efficiently heated and melted to form the ultrafine particles. The gaseous tungsten arc from the 1st electrode 4 deflect largely and therefore, the generated ultrafine particles are quickly conveyed in the specified direction. The ultrafine particles are thereby introduced into as conveying pipe 7. Since the arc is generated between the two electrodes 4 and 5, the ultrafine particles are obtainable even with a nonconductive material. n COPYRIGHT: (C)1987,JPO&Japio |
