| Shrnutí: | Title screen The effect of magnetite, added in the form of pyrite cinders, on the physicomechanical and radio-absorbing properties of synthesized glass-composite was investigated by means of ‘cold foaming.’ The substitution of magnetite for glass powder in the initial liquid-glass composition decreases the foaming factor from 210 to 130%, which is due to viscosity reduction in the composition on account of the size of the additive particles (up to 160 µm) and their high density (5100 kg/m3) as well as their porous structure. It was established that magnetite content =10% is optimal for obtaining a material possessing radio-absorbing properties. A porous glass composite with 10% magnetite and average pore size 1.2 mm possesses a coefficient of absorption of electromagnetic radiation at high frequencies (120 – 250 GHz) that is 10% higher, on average, compared to a composite without an additive.
