FIELD: refractories industry. SUBSTANCE: described is preparation and use of highly concentrated quartz glass suspensions having density of 1.89-1.93 g/cubic cm to which grainy quartz glass aggregate with particle size of 0.1-2.0 mm is added in amount of 30-45% Gainy aggregate is first subjected to moistening to moisture content of 2-5% by mixing it with discharge from centrifugal casting of quartz refractories. After mixing the compound, products are molded by centrifugal casting method and heat treated at 1150-1200 C. EFFECT: refractories having structure of material uniform along thickness. 2 cl
