Аннотация: The BeO-based ceramics with adding micro and nano-size powders of TiO2 have a number of unique properties such as a high specific thermal conductivity, high insertion loss values for an electromagnetic wave propagating through the material under research. All of these features of BeO-based ceramics give us the possibility to use thПоказать полностьюis material for a high power load realization in the RF range. The investigation of the influence of the sintering temperature of ceramics on electrophysical properties of studying materials in the frequency range from 8 to 12 GHz has been presented in this article. The vector network analyzer R&S ZVA50 with a set of measuring equipment consisting of the waveguide transmission line WR90 standard and calibration kit for performing TRL calibration procedure has been used for performing measurement of electrodynamics properties of researching materials. Structural characteristics of BeO-based ceramic samples with the addition of TiO2 micro and nanopowders were investigated using scanning electron microscopy and differential thermal analysis. The density of research samples was defined by the hydrostatic weighing method. The comparison of ceramic samples with different sintering temperatures of ceramics 1550 0C and 1660 0C was presented in the article. The frequency dependences of the complex dielectric permittivity of studied samples are given. © 2022 IEEE.
