Abstract
Investigations of the changes of structure, specific surface and true density of following high-magnesia rocks at heat treatment have been performed: brucite rocks, magnesite, hydromagnesia rocks, amorphous magnesite. It has been revealed that to obtain chemically active magnesium oxide, which is used for synthesis of high-refractory materials and obtaining magnesia binder, it is necessary to burn at low or moderate temperatures in the temperature range of 500-800 °C. Increase of temperature more than 800 °C leads to obtaining densely sintered cubic magnesium oxide with the periclase structure.
