This paper attempts to increase the heat resistance of MKS-83 mullitecorundum parts produced to specification (TU) 14-8-140-75. Mullitecorundum chamotte, electrocorundum, Latnaya clay, and fused mullite were used as the original materials. The parts with fused mullite have higher heat resistance than the parts without the addition but for them the open porosity is somewhat higher and the compressive strength is lower. The maximum heat resistance of the parts with fused mullite was obtained with firing at 1580 C. The lots produced of mullite-corundum parts structurally reinforced with nonisometric grains of fused mullite had high heat resistance.
