METHOD FOR DENSIFICATION AND SPHEROIDIZATION OF SOLID AND SOLUTION PRECURSOR DROPLETS OF MATERIALS USING MICROWAVE GENERATED PLASMA PROCESSING |
摘要 |
A method for processing feed material to produce dense and spheroidal products is described. The feed material is comprised of powder particles from the spray-drying technique or solution precursor droplets from ceramic or metallic materials. The feed material is processed using plasma generated from a microwave. The microwave plasma torch employed is capable of generating laminar flow during processing which allows for the production of spheroidal particles with a homogenous materials distribution. This results in products having improved thermal properties, improved corrosion and wear resistance and a higher tolerance to interface stresses. |

1. A method of producing spheroidal and dense powder product particles extracted from plasma exhaust gas following injection of feed materials consisting of powder particles or solution precursor droplets using a microwave plasma and which method comprises:
a) introducing axially feed material through a materials feeder into an axisymmetric microwave plasma torch; b) processing said feed material by exposing it to high temperature profile within the microwave generated plasma; c) filtering said exhaust gas of said microwave generated plasma; and d) extracting powder products from said filtered exhaust gas. |
