Synthesis and Study of Dielectric Properties of Composite Material Consisting of Glass Ceramics Based on Pearlite and TiO₂

A method for low-temperature synthesis of a composite material glass-ceramic—TiO₂ is proposed. Frequency dependencies of the dielectric permittivity and dielectric losses in the frequency range of 0–20 MHz are investigated. It is shown that an increase in the TiO₂ content in the composite material leads to an increase in dielectric permittivity and a decrease in dielectric losses. The structure and phase composition of the composite material were studied using X-ray diffraction, showing that during low-temperature heat treatment, the components of the composite material do not form new phases, and the obtained material can be represented as a mixture of non-interacting components randomly distributed in space.
