Горение частиц при взаимодействии излучения гиротрона со смесью порошков металл/диэлектрик

Abstract

As a result of interaction under normal conditions in an air atmosphere of a microwave pulse of a gyrotron with a mixture of Al/Al2O3 powders, ceramic particles of morphology microprocesses are synthesized. A variant of a multi-stage process for the development of physical and chemical processes in a reactor, taking into account ignition. After the end of the microwave pulse, a cloud is observed consisting of hot aluminum oxide particles and burning aluminum particles. A certain influence of the combustion process of aluminum particles on the products of plasma-chemical synthesis. The paper also determines the average velocity of particles from the powder mixture, the burning time of aluminum particles, the surface temperature of the particles of the powder mixture, and the temperature of the gaseous medium in the upper part of the plasma-chemical reactor.
