PROBLEM TO BE SOLVED: To provide a high-frequency plasma synthesis method.SOLUTION: In the method, by utilizing hot plasma technology, by making, as a high-temperature heat source, a high frequency plasma synthesis apparatus, and by the hot plasma treatment and the high-temperature, an aluminum dross is purified and alumina (AlO) is precipitated from the aluminum dross, to produce an alumina ceramic powder, and thereby simultaneously achieving the treatment of aluminum dross and the production of alumina, and the aluminum dross is converted to a salable product. Said apparatus is composed of a feeder and a high-frequency generator, a hot plasma source, a reaction chamber, a powder collecting unit and a vacuum pump.SELECTED DRAWING: Figure 1 |
