摘要：

The phase composition in the technologically-modified MgO-Al2O3 nanoceramics sintered at 1200 degrees C and 400 degrees C for 2 h and 9 h are investigated using X-ray diffraction and high-resolution X-ray photoelectron spectroscopy. It is shown that structural perfection of MgO-Al2O3 ceramics increases with sintering temperature and their duration, which manifests reducing the content of the additional phases. Modification of ceramics obtained at 1400 degrees C by increasing the sintering duration leads to increase of MgO phase. The core-level O 1s spectrum in MgO-Al2O3 ceramics allows to identify the chemical state of atoms and makes it possible to obtain confirmation about addition phases in ceramics.
