【 摘 要 】

The phase composition, structure, and physical and mechanical characteristics of refractory aluminosilicate SHS materials (AS materials) were investigated taking into account the properties of initial components and the production method. Computational methods were used to reveal macrokinetics of processes and determine the possible formation of mullite structures and corundum in aluminosilicate refractory SHS materials during the synthesis reactions. Heat losses caused by the small thickness of a coating or the walls of the material between pores were found to have a significant effect on the synthesis reaction in thin coatings and porous AS materials, as well as the on the formation of various chemical compounds.
