The formation of a composite ceramic based on the system SiO2 – Al2O3 – TiO2 with the addition of γ- and α-Al2O3 nanostructural powders during heat treatment in the temperature range 1300 – 1400°C is investigated. It is established that the introduction of γ-Al2O3 reactive nanostructural powder stimulated a solid-phase reaction between the silica and alumina with mullite being formed, while the addition of α-Al2O3 powder led to the formation of aluminum titanate. These processes altered the phase composition and the porous and crystalline structure of the composites and increased their physical – chemical and thermophysical properties.
