Abstract
The present invention relates to the production of ultrafine powders using a microwave plasma apparatus and chemical synthesis technique. Microwaves generated by a magnetron ( ) are passed through waveguides ( ) before they arrive at the head of a plasmatron ( ). 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 ( ). The reaction products are quenched rapidly in a reactor column ( ) into ultrafine powders.
