Abstrakt: An investigation of the deformation properties of high-alumina refractories showed that creep in a reducing medium (containing up to 8% CO) is greater than in an oxidizing medium, viz. by a factor of 1.3 for mullite products, 1.7 for mullite-corundum specimens, and 2.2 for commercial grade mullite-corundum refractories. The creep of these refractories increases 1.2-1.4 times with an increase in the pressure of the gaseous medium to 1.5 atm. The apparent density of high-alumina refractories increased in the tests with the deformation and with a change from an oxidizing to a reducing medium. [ABSTRACT FROM AUTHOR]
