The paper presents the results of a study on the synthesis of magnesium oxide xerogels. In the synthesis, the sol-gel method was used, in which magnesium methoxide was applied as a magnesium precursor. The obtained magnesium hydroxide was subjected to the thermal dehydration process to obtain magnesium oxide particles. The influence of xylene addition during magnesium methoxide hydrolysis on the structure of the magnesium hydroxide and oxide was investigated.

W pracy przedstawiono wyniki badań nad syntezą cząstek kserożeli tlenku magnezu. W procesie syntezy zastosowano metodę zol-żel, w której wykorzystano metanolan magnezu jako prekursor tlenku magnezu. Otrzymany wodorotlenek magnezu poddano procesowi termicznej dehydratacji w celu otrzymania tlenku magnezu. Zbadano wpływ dodatku ksylenu na strukturę wodorotlenku i tlenku magnezu.
