摘要：

The principal factors controlling the spheroidization process of Al2O3 powder in the induction plasma are the position of the powder injector, the powder feed rate, and their interactions. A higher level of powder feed rate (4.2 kg/h) has been achieved at the r.f. plate power of 40 kW with the application of response surface methodology (RSM). Under these loading conditions, the spheroidization of the Al2O3 powder of -44 + 15 mu m size attained 94.9%, while for Al2O3 of -89 + 44 mu m size, 83.3% spheroidization was achieved.
