Sažetak
High-energy dry ball-mill and post-anneal processing were applied to synthesize MgTiO3 and Mg2TiO4 single crystalline phases from the predetermined compositions of MgO-TiO2 powder mixtures. Also, the experiments were peformed to show that it is possible to prepare MgAl2O4 single crystalline phase from the predetermined composition of Al2O3-MgO powder mixture just by employing high-energy dry ball milling, i.e. without the post-annealing of the milled samples. However, fully developed single crystalline phases of MgTiO3 and Mg2TiO4 were obtained after post-annealing of the milled samples for one hour at 900 0C and 1200 0C, respectively.
