MICROWAVE PLASMA CHEMICAL SYNTHESIS OF ULTRAFINE POWDERS |
摘要 |
<p>The present invention relates to the production of ultrafine powders using a microwave plasma apparatus and chemical synthesis technique. Microwaves generated by a magnetron (1) are passed through waveguides (2) before they arrive at the head of a plasmatron (3). These high energy microwaves ionize a plasma gas, thus releasing large amounts of energy. The energy thus released is utilized to initiate and sustain chemical reactions between the desired elements being pumped in a spiral pattern into the plasmatron (3). The reaction products are quenched rapidly in a reactor column (4) into ultrafine powders.</p> |
