To the Problem of the Creation of High-Temperature Radio-Absorbing Composite Ceramic Materials

The main directions in the creation of high-temperature radio-absorbing ceramic materials that can be used to create new functional materials for space, aerospace, electronic engineering and in medicine are considered in the article. A well-founded choice of a high-temperature dielectric matrix and ferroelectric additive for obtaining a gradient composite radio-absorbing material is carried out. The results of studies of the ferroelectric impurities concentration influence on the physical and dielectric properties of composite ceramics obtained for ceramic technology are presented. Based on the studies of the phase composition and microstructure of the composite ceramics compositions studied, it was possible to establish a relationship between the properties, the phase composition and the structure of the obtained ceramic materials with different values of the dielectric constant.
