Questions are discussed for the occurrence of an electrically conducting phase in composite (BeO + TiO2)-ceramic with a different amount of added TiO2 leading to UHF-radiation absorption. Strongly reduced TiO2 acts as the absorbing component. Composite (BeO + TiO2)-ceramic compared with (Al2O3 + TiO2)-ceramic is distinguished by increased thermal conductivity and electrical conductivity a higher microwave radiation attenuation coefficient and thermal stability, and may be used in radio electronic technology as an efficient UHF-radiation absorbent, and in other fields of contemporary technology.
