Двухслойные пористые керамические материалы для микрофильтрации дисперсных систем

Abstract

The compositions and technological parameters of obtaining filtering corundum and quartz ceramic materials with functional membrane coatings obtained in the Al2O3–ZnO, Al2O3–Fe2O3, Al2O3–CuO and Al2O3–MnO2 systems were developed; the regularities of the process of formation of a layered porous permeable structure have been established in conjunction with the physicochemical properties, phase composition and performance characteristics of filter materials. Scientifically substantiated and experimentally confirmed the desirability of the use of polyphenylsiloxanes as a binder to obtain porous permeable corundum and quartz ceramics.
