Sažetak
The process of isothermal sintering of magnesium oxide obtained from seawater by substoichiometric (where precipitation of magnesium hydroxide took place with 80 % of the stoichiometric quantity of dolomite lime) and by overstoichiometric precipitation (which took place with 120 % of the stoichiometric quantity of dolomite lime) was examined, with addition of 1, 2 and 5 mass % TiO2, at temperatures in the range 1550 oC - 1750 oC, with 1, 3 and 5 hours of soaking at the maximum temperature. The process was followed by determination of the product density, as well as of the B2O3 content in the samples sintered. The results indicate that, besides affecting favorably the density of samples sintered, the addition of TiO2, with increasing temperature and soaking time, also significantly reduces the B2O3 content in sintered magnesium oxide obtained from seawater A statistical analysis of data obtained has been performed with the "Statistica" package in order to obtain the model of density of sintered samples of magnesium oxide relative to temperature and time of isothermal heating, and the percent of added TiO2.
