| Popis: | The forsterite and spinel formation reactions were examined in the process of isothermal sintering of magnesium oxide obtained from seawater and of magnesium oxide p.a. The sintering process was carried out in the temperature range from 1300 to 1600 oC, with the duration of isothermal sintering being 5 h. The reaction flow was examined by quantitative and qualitative X-ray analysis and by thermodynamic analysis of results obtained, in order to establish the conditions of formation of these minerals in various samples examined and relationship between the quantity of minerals formed and the product properties. The specific surface, chemical composition, and dislocation density were determined for the magnesium oxide samples examined. |
