Abstract
Structural and phase transformations during the formation of a two-layer porous material by sintering aluminum oxide microspheres on a large-pore aluminum-silicate substrate are studied. It is established that the condition for interaction of microspheres is a liquid-phase sintering mechanism that allows obtaining membrane layers of a regular structure. As a result of sintering of aluminum oxide microspheres doped with a manganesecontaining complex with additives of silicon oxide, along with a-Al2O3 (corundum), sillimanite of orthorhombic modification is formed in the amount of 27%, hexagonal quartz-26%, tetragonal pyrolusite – 10% and hexagonal SiC (moissanite) – 6%. Increasing the regularity of the membrane layer pores contributes to the constancy of the filtration period between regenerations.
