IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishSimultaneous TG–DSC measurements have been used to study the solid state reaction in the system SnC2O4–4MgCO3*Mg(OH)2*xH2O(Sn:Mg = 0.5).The results obtained with physically prepared mixture and with mixture mechanically activated by high-energy milling are compared. Synthesis of the compound Mg2SnO4 has been attempted starting from both type of mixture: Mg2SnO4 forms by annealing the activated mixture at temperatures between 850 and 1000 °C while it can hardly be obtained from physical mixtures even by thermal treatment at temperature as high as 1300–1350 °C. Mg2SnO4 prepared by annealing the activated mixture has been characterized by diffuse reflectance FT-IR spectroscopy, modulated temperature differential scanning calorimetry, scanning electron microscopy, and specific surface area measurements (B.E.T. method).
