Abstract

Compositions of porous compounds (density 300 to 500 kg/m3) for thermal insulation of hot surfaces up to 1300oC were developed. Ordinary clay (at a clinkering temperature of 1150...1200oC), was chosen as a main substance for structure formation. The increasing thermo-resistance fraction of a ceramic matrix composite was obtained via embedding a refractory clay and dinas fillers into compositionб as well as by means of optimizing the relationship «ordinary clay – high aluminous cement», for which the formation of additional amount of mullite phase is observed when first heating of material.
