Influence of heat treatment in vacuum on shungite shielding properties
Abstract
The research results of structure, chemical composition, reflection and transmission coefficients of powder shungite after heat treatment at 900 °С for 2 h are presented. According X-ray diffraction study, orthoclase was formed, modifications of carbon saved. Transmission coefficient increased in 12 dB in the range 8-12 GHz.
