Both non-activated and activated samples were sintered at different temperatures (1250, 1300, 1325, 1350 and 1375) °C for (1, 2, 3 and 5) h and the formation of a mullite phase was examined with an X-ray diffraction analysis. It was determined that the mechanical activation increased the quantity of the mullite phaseMešanice prahov glinice in kremena so bile 2 h mehansko aktivirane v planetarnem mlinu. Neaktivirani in aktivirani vzorci so bili sintrani (1, 2, 3 in 5) h pri različnih temperaturah (1250, 1300, 1325, 1350 in 1375 °C), z rentgensko difrakcijsko analizo pa je bil preiskovan nastanek mullitne faze. Ugotovljeno je bilo, da mehanska aktivacija poveča količino mullitne fazeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
