The scope of this work was observing dimensional and heat transfer changes in   ZnTiO3 samples during heating in nitrogen and air atmosphere. Interactions of   bulk specimens with gaseous surrounding induce microstructure changes during   heating. Sintered ZnTiO3 nanopowder samples were submitted to subsequent   heating. Dilatation curves and thermogravimetric with simultaneous   differential thermal analysis TGA/DTA curves were recorded. Reheating was   performed in air and nitrogen atmospheres. Reheated samples obtained at   different characteristic temperatures in air were analyzed by X-ray   diffraction (XRD). Microstructures obtained by scanning electron microscopy   (SEM) of reheated sintered samples are presented and compared. Reheating in a   different atmosphere induced different microstructures. The goal was   indicating possible causes leading to the microstructure changes. [Projekat   Ministarstva nauke Republike Srbije, br. OI172057 i br. III45014
