In order to understand the sintering process in magnesium oxide and to obtain a mathematical model describing behaviour, tests were carried out with different quantities of SiO2, Al2O3 and TiO2 added to magnesium oxide obtained by substoichiometric and overstoichiometric precipitation of magnesium hydroxide in sea water with dolomite lime.

The isothermal sintering temperature ranged from 1300°C to 1600°C. The process of isothermal sintering was examined by determining densification and sample density, and by mathematical processing of results.

The B2O3 content in samples sintered was examined in forms of its dependence on the isothermal sintering temperature, on the quantity of TiO2 added, and on the way magnesium oxide was obtained. The results were processed thermodynamically.
