Phase composition of the carbonatization product of nanocrystalline KO2 deposited on a glass fiber matrix

Аннотация

The phase composition of the carbonatization products of nanocrystalline KO₂ deposited on a glass fiber matrix has been studied using differential thermal analysis, X-ray diffractometry, and Raman spectroscopy. The results demonstrate that the possible carbonatization products of potassium superoxide and alkali nanocrystals are potassium carbonate (K₂CO₃), potassium bicarbonate (KHCO₃), and mixtures of these, depending on the reaction temperature. No new phases or chemical compounds with glass fiber were detected.
