Abstract

At this research micron powder of alpha-iron had been irradiated by microwaves radiation with frequency of 9 GHz and power density of 80 W/cm2 for 4-40 seconds. It was found that the value of start oxidation temperature of powder was characterized by fluctuating values in the range 150-250?C with increase of exposure dose. In addition, the specific thermal effect of powder oxidation varied from 5870 to 7505 J/g with increase of irradiation absorbed dose. The degree of powder oxidation varied from 34.5 to 46.95%. The probable cause of these regularities is an increase the activity of iron powder and subsequent decrease of it under high power density microwaves.
