FIELD: ceramic materials. SUBSTANCE: charge has, %: Al2O3 73-95; Al2TiO5 2-25; CaO 0.3-0.7; CuO 0.5-2.5. Use of proposed charge promotes enhanced mechanical strength at retained high thermal stability as a result of aluminium titanate decomposition and sintering up to zero opened porosity at the range of temperature 1250-1280 C. Bending strength is 320-400 MPa at 20 C and 180-270 MPa at 1000 C, ΔT-680-750°C is 680-750 C. EFFECT: enhanced quality of charge. 1 tbl
