abstract = "The aim of this paper was mechanochemical preparation of magnesium titanates. Powder mixtures of starting oxides MgO and TiO2 were mechanically activated in a planetary ball mill for the time interval from 0 to 160 minutes. Structural, stereological, thermal characterizations were performed on produced powders. The effects of activation on morphology were investigated by scanning electron microscopy and particle size analyses, while the changes in the phase composition were determined by X-ray diffraction. It is determined that the first traces of MgTiO3 became detectable after 40 minutes of milling, while after 160 minutes the pure magnesium titanates were noticed. The differential thermal analyses and thermo gravimetric analysis, in temperatures range from 25 oC to 1100 oC, has been performed in order to investigate thermal behavior of the mixtures., Cilj ovog rada je bio dobijanje čistog magnezijum titanata mehanohemijski, putem reakcije u čvrstom stanju. Smeša polaznih oksida MgO i TiO2 je podvrgnuta mehaničkom tretmanu u vremenskim intervalima od 0 do 160 minuta u visokoenergetskom planetarnom mlinu. Dobijeni prahovi su detaljno okarakterisani termijski, stereoloski i strukturno. Morfologija prahova je ispitana SEM analizom i praćenjem raspodele veličina čestica na laserskom analizatoru, dok su promene u faznom sastavu ispraćene snimanjem XRD. Utvrđeno je da se prvi tragovi magnezijum titanata javljaju već nakon 40 minuta aktivacije, dok je nakon 160 minuta prisutan čist magnezijum titanat. Radi određivanja karakterističnih temperatura reakcija koje se odigravaju u aktiviranim sistemima snimljeni su termogrami u temperaturnom intervalu od sobne do 1100 oC.",
