Comparison of the Microwave Absorption Characteristics of

AbstractWe provide an understanding of the microwave absorption characteristics of hematite, magnetite and pyrite by measuring and comparing the microwave heating rate, dielectric and magnetic properties and the absorbed microwave energy The three methods have their own advantages and disadvantages, and supplement each other Magnetite showed the strongest microwave absorption.
