The study shows that in order to significantly reduce the thermal conductivity coefficient of heat insulating materials made of staple basalt raw fibers, it is necessary to grind and clean them from impurities by liquid method. Within the research, we found that tubing heat insulating coating has the insulation wall thickness and mass per unit length limitations. In this paper we give the results of studying high-temperature and low-density heat insulation of short basalt fibers and alumina bundles.
