The processes occurring during the formation of hollow microspheres based on ash and slag waste from thermal power plants of the Kemerovo region in a thermal plasma flow are considered. The results of physical and chemical studies (scanning electron microscopy, energy dispersive X-ray and infrared spectroscopy) of the raw material and the resulting microspheres on its basis are presented. A comparative analysis of hollow microspheres obtained by the traditional method in chamber furnaces of thermal power plants of the Kemerovo region and microspheres obtained using thermal plasma has been carried out.
