Design of a New Method for Obtaining Thermal Insulation Blocks from Hydrosilicate

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

Design of thermal insulation from porous materials based on hydrosilicates is a promising area of researches. In this paper, the formation of pores is analyzed and the advent of new highly porous heat-insulating materials on the basis of hydrosilicates is proposed. The determination of the thermophysical properties of the studied highly porous materials is based on empirical laboratory investigations of the samples obtained. An analytical study of the formation of pores is carried out. The results of the research on the preparation of a new highly porous heatinsulating material on the hydrosilicate basis are presented. The thermal conductivity of this thermal insulation was found to be equal to 0.114–0.119 W/(m·K), and its specific heat at 22°С, to 1.33–1.41 kJ/(kg·K). The obtained results confirm that the developed heat-insulating material meets the requirements upon materials of this kind. From the proposed hydrosilicates, thermal insulation has been created that is used at JSC Motor Sich for special conditions of the operation, which confirms the practicality of the present researches.
