It was investigated electrophysical, mechanical and protective properties of synthesized composite materials based on hexaferrite and aluminates of barium according to the created technology, which were sintered at 1300-1350°С. It was shown that composite materials have binding properties, high coercive force is up to 6000 – 6500 Oe and compressive strength for the 7 day is up to 75 – 85 MPa. It was found that synthesized composite materials have necessary magnetic and high-strength properties and provide the effective protection of biological and technical objects against electro-magnetic radiation in frequency range from 70 to 90 GHz reducing the effect of electro-magnetic radiation on 26 dB.
