Abstract :
In this paper, a new rapidly quenched atomization equipment, high pressure gas centrifugal rotation disc (HPGCRD) is reported. Various kinds of amorphous, quasi-crystalline and micro-crystalline powders were prepared by the HPGCRD device. The average diameter of the powders prepared by the HPGCRD was in the range of 5–15 μm. SEM observation showed that the shapes of the powders appeared sphere or quasi-sphere. The cooling rate was theoretically estimated to be 105–107 K/s based on the analysis of practical atomization process.
