Abstract

The rheotechnological properties of mixed suspensions in the SiO2 - Al2O3 system obtained by the method of mixing of individual suspensions of molten quartz and alumina are described. Some properties of the materials after their heat treatment at 1000 – 1300°C are investigated. The ranges of compositions (30 – 40% Al2O3, 60 – 70% SiO2) in which the parameters of thermal expansion of the materials are 2 – 3 times lower than those calculated under the condition of additivity are determined. The obtained materials possess an elevated mechanical strength.
