Composite (BeO + TiO2)-Ceramic for Electronic Engineering and Other Fields of Technology (Review)

Abstract

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.
