Materials with MgO nanocrystalites were prepared by sol-gel synthesis. Alcogels were dried either supercritically at 538 K or in supercritical CO₂. Conventional drying was also applied. Calcination of dry gels at 723 K under vacuum yielded MgO nanocrystallites. In the studied materials the amorphous phase was also stated. MgO nanocrystallites are immersed in amorphous matrix. Structure studies were performed by X-ray diffraction, scanning and transmission electron microcopies. Nitrogen adsorption/desorption measurements were also performed. Morphology of supercritically dried samples is similar; rough surface of powder particles is observed. Powder particles of conventionally dried sample are more compact. Size of MgO crystallites is generally similar for all samples and equal to about 7 nm despite of drying conditions of alcogels. Specific surface area and volume of mesopores is the greatest for sample supercritically dried at 538 K.
