Abstract
The effect of the addition of magnetite in the form of pyrite stubs on the physico-mechanical and radio-absorbing properties of the synthesized glass composite by the method of “cold” foaming is considered. Replacing glass powder with magnetite in the initial liquid-glass composition reduces the foaming coefficient from 80 to 20 %, which is due to a decrease in the viscosity of the composition due to the particle size of the additive (160 ?m), their high density (5100 kg/m3) and porous structure. It has been established that the optimal content of magnetite for obtaining a material with radio-absorbing properties is no more than 10 %. A porous glass composite with an average pore size of 2, containing 10 % magnetite, has an absorption coefficient of electromagnetic radiation in the high-frequency range (120 – 250 GHz) on average 10 % more than a composite without an additive.
