摘要

研究了复合（BeO + TiO2）陶瓷在 8 - 12 GHz 频率范围内的电动特性。在 BeO 混合物中引入 TiO2 微粉和纳米粉体后，陶瓷烧结温度从 1823 K 提高到 1933 K，通过提高介电常数虚部和实部的模量，有可能影响（BeO + TiO2）陶瓷作为微波辐射吸收成分的效率。在 1073 K 的氢气环境中进行的额外还原退火进一步改变了陶瓷的导电性，增强了其吸收超高频辐射的能力。

Electrodynamic Properties of (BeO + TiO2)-Ceramics in the Centimeter Wavelength Range

Electrodynamic properties of composite (BeO + TiO₂)-ceramics in the frequency range 8 – 12 GHz are studied. An increase in ceramic sintering temperature from 1823 to 1933 K after introducing TiO₂ micro- and nanopowders into BeO mixtures makes it possible to influence the efficiency of (BeO + TiO₂)-ceramics as an absorbing component of microwave radiation by increasing the modulus of imaginary and real parts of the dielectric constant. Additional reduction annealing in a hydrogen atmosphere at 1073 K further changes the ceramic electrical conductivity and enhances the effect of its ability to absorb UHF-radiation.
