The natural minerals of the Tebinbulak deposit, which are used as heat-insulation materials, were investigated. Their expansion coefficient depends on the raw grain size and ranges from 3.47 to 7.67. The structure of the material was studied by means of x-ray diffraction and infrared spectroscopy. The chemical composition was determined by the microprobe method, and the phase transformations on heating were determined by means of differential scanning calorimetry. The information obtained made it possible to conclude that this micaceous mineral is at the initial stage of metamorphism, i.e., a disordered interlayer structure of phlogopite/vermiculite (hydrophlogopite). This information is important for studying how the structure of hydromicas affects the possibility and nature of their swelling on heating.
