Abstract
Research on thermal stability of mineralogical types of micas deals with materials with high thermal stability. At high temperatures, as a result of water release, mica loses its transparency, swells, stratifies and becomes mechanically unstable. Due to these changes, the properties of mica worsen. Phlogopites can vary in their quality. Therefore, when phlogopite is used in materials and devices operating at very high temperatures, it is necessary to use the type of mica whose thermal resistance meets the operating conditions.
