Original Abstract

Composition and morphology of filter ceramics was investigated during filtration of steel deoxidised by aluminium. Filtration was realised with use of filters based on oxidic ceramics Cr2O3, TiO2, SiO2, ZrO2, Al2O3, 3Al2O3.2SiO2 and MgO.Al2O3. It was established that change of interphase (coating) occurs during filtration of steel on the surface of capillaries of ceramics, where content of basic oxidic component decreases. Loss of oxidic component in the coating is replaced by increase of oxides of manganese and iron and it is great extent inversely proportional to the value of Gibbs' energy of oxide, which forms this initial basis of ceramics.
