Preparation of Ceramics Added Tailings and Electromagnetic Properties

Abstract

Electromagnetic functional ceramics added iron tailings were prepared using the burning method, and the EMWA properties were tested through the arch testing method at 2–18 GHz. It was found that the minimum reflection loss (RL) peak was −16.0 dB at 17.0 GHz, and that the thickness of ceramics was 2.00 cm. With the thickness increasing, the RL value went up, and the RL peak number also increased. The magnetic and dielectric losses of tailing powders acting as an absorbent were the main mechanisms of EMWA properties for ceramics, which could be used for electromagnetic radiation protection of architectural spaces.
