Description
Summary:Investigations of a foam glass crystal material synthesized from raw siliceous earth material by the two-stage method at temperatures below 950°С have demonstrated the improvement of its physicomechanical properties in comparison with foam glass synthesized from glass cullet. This material actively interacts with microwaves and can be used for the development of protective screens reducing the adverse effect of microwaves on biological objects, unechoic chambers, and rooms with low level of electromagnetic background noise. Spectra of the transmission and absorption coefficients and of the complex dielectric permittivity for frequencies in the range 26–260 GHz are presented. The observed effects demonstrate the existence of regions with partial and total reflection arising on the glass–pore boundary and of the microwave interaction with ultradisperse carbon particles that remain after foaming with incomplete frother transition from the soot to the gas phase.
