Effect of Microwave Radiation on the Thermal Properties of the Electroexplosive Copper Nanopowder

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

At this research, copper nanopowder was irradiated by microwaves radiation with frequency of 2.85 GHz and power density of 8 kW/cm2 for 5 seconds. It was founded 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.
