In the Bayer process for obtaining alumina, red mud is a by-product (solid waste from the leaching of bauxite). Using red mud as a raw material mixture component to obtain sintered products, a cheap raw material for construction and ceramics would be obtained, and the environmental problems resulting from the frequent deposits of red mud in pools would be solved. Based on the overall results of our examinations in this study, it can be concluded that the change of basic parameters, sintering temperature and binder content (illite-kaolinite clay), can provide satisfactory characteristics for the sintered product in terms of mechanical properties, volume shrinkage during sintering and total porosityČlanek obravnava preiskavo lastnosti sintranih proizvodov na osnovi rdečega blata v odvisnosti od temperature sintranja in vsebnosti veziva (glina ilit-kaolinit). Rdeče blato (trden odpadek pri izpiranju boksita) je stranski proizvod pri Bayerjevem procesu pridobivanja glinice. Rdeče blato kot surovina v mešanici za sintranje komponent je poceni material za gradnjo in keramiko, rešuje pa tudi okoljske probleme, ki izvirajo iz rednega odlaganja rdečega blata v bazene. Na podlagi rezultatov te študije se lahko sklene, da spreminjanje osnovnih parametrov, temperature sintranja in vsebnosti veziva (glina ilit-kaolinit), omogoča zadovoljive lastnosti sintranega proizvoda glede mehanskih lastnosti, krčenja prostornine med sintranjem in celotne poroznostiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
