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

摘要

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.
