Controlled Synthesis and Microwave Electromagnetic Properties of Micro - nano MnO2 Powder

摘要

The manganese dioxides,in combination with their novel chemical and physical properties,have paved the way for their wide use as catalysts and electrochemical materials,but the microwave absorption properties of MnO2 have not been exploited.Our research group has found that manganese dioxides own excellent dielectric loss.However,the magnetic loss is relatively low.Besides,the low frequency absorption performance is relatively
