Influence of TiO₂:ZrO₂ Bi-Component Additive on the Mechanical Properties of Glass-Ceramic Material Based on Perlite

The influence of a two-component TiO₂:ZrO₂ addition on the mechanical properties of a glass-crystalline material synthesized on the base of perlite has been studied. A relationship has been established between Young’s modulus, microhardness, and the content of the TiO₂:ZrO₂ addition to the original batch. The kinetics of crystallization of the resulting material were studied using the method of non-isothermal differential thermal analysis (DTA). Based on the results of SEM studies, it was established that the addition of TiO₂:ZrO₂ results in an increase in the concentration of nucleation sites and a decrease in the size of the resulting crystallites, which ultimately is the physical reason for the increase in the microhardness of the synthesized glass ceramics.
