Potential Advantages for Millimeter-Wave Heating of Powdered Metals

Abstract

Based on electromagnetic induction heating, an interaction model of microwaves with powdered metal has been established. The formulae of attenuation coefficient, heating rate and heating conversion efficiency are obtained and analyzed. The results of calculations show that millimeter waves may be able to overcome the obstacle caused by smaller skin depth and have strong advantages for the microwave heating of powdered metals. Experiments are done for comparison with present theory.
