The physicomechanical and structural properties of sintered materials
based on Al2O3-MnTiO3, Al2O3-MnO2-SiO2, and Al2O3-MnO2-TiO2-SiO2 syste
ms were comparatively analyzed. An effect of slowing of recrystallizat
ion sintering when titanium and silicon dioxides are simultaneously ad
ded to the batch was detected. The effect of the methods of adding sil
icon dioxide to the batch on the microstructural and strength properti
es of the sintered ceramic of the Al2O3-MnO2-TiO2-SiO2 system was esta
blished.
