The source of carbon was propylene, which was obtained by dehydration of propane and nitrogen-containing compounds: acetonitrile and ethylenediamine. Complex Si Al Fe Mo-O oxides are also obtained by the pyrogenic method in a hydrogen-air burner. It is shown that reducing the size of the dispersed catalyst for the synthesis of carbon nanotubes (BNT) of Al Fe Mo-O content increases their specific surface. The KNT synthesized by the KI spectrum is modified by nitrogen. It has been shown that the use of BNT with different specific surface and their modified forms of oxygen and nitrogen for the reinforcement of fiberglass plastics leads to a change in absorption and reflection coefficients of composite materials in the range of frequencies 8-80 GHz.
