Sažetak
This study has examined the process of sintering of Mg0 samples (80 % precipitation) obtained from seawater at a temperature of 1500 ºC in order to determine the influence of nano- TiO2 on their properties (density, porosity), chemical composition and microstructural characteristics after sintering. The magnesium oxide samples were prepared by rinsing of the Mg(OH)2 precipitate with the combined rinsing method (2+3) (rinsing 2 times with distilled water of pH of 5.88 and 3 times with alkalized distilled water of pH of 12.50) in the process of decantation, and 5 times with fresh distilled water of pH of 5.88 on filter paper. The results indicate that the method of rinsing of the magnesium hydroxide precipitate significantly affect the chemical composition of samples, primarily with regard to the CaO and B2O3 content. Further, the process of sintering of magnesium oxide and the influence of the nano-TiO2 addition (ω =1, 2 and 5%) on its properties and microstructure at sintering temperatures of 1500 (1 h) was examined. SEM/EDS analysis confirmed the formation of periclase grain and its direct bonding. CaTiO3 and MgTiO4 are separated in the form of a thin layer over the periclase grain boundary surface during cooling. Microstructure of the MgO samples with the addition of nano-TiO2 becomes more compact which have positive influence on porosity and density of the samples.
