Abstrakt: Samples of the crust formed on the lining of a rotating kiln in firing of mullite-corundum chamotte were investigated. The crust consists of a mullite-glass mass and grains of corundum. Depending upon the medium in the furnace it has different structures, phase compositions, and colors. The white crust is less sintered and has a porous and loose structure. The size of the pores is up to 2.4×1.36 mm. The structure of the black crust is monolithic porous with a pore size up to 1.2×0.47 mm. The rust-colored crust has a coarse porous structure and a pore size of up to 1.7×0.9 mm. The crust is nonuniform in phase composition. The greatest mullite content is in the white crust and the least in the rust-colored. [ABSTRACT FROM AUTHOR]
