赤泥黑色玻璃晶化过程的红外光谱研究
Infrared Spectra of Crystallization of Glasses Using Red Mud as Raw Materials
摘要
Abstract
FTIR absorption spectra and XRD were used to study the structure of glasses using red mud as raw materials. The results indicate that Ca(Fe, Mg)Si2O6 and 2CaO2O32 precipitate as primary and minor crystalline phase respectively on crystallization processes of glasses. Glasses have interlinked SiO4, AlO4 and Fe3+O4 tetrahedra as their most fundamental units with K+, Na+, Fe2+ and some Fe3+ ions acting as charge balancing cations. The short-range order which is similar to the structure of Ca(Fe, Mg)Si2O6 exists in the glasses and has the precursor structures of primary crystalline phase. With the increase of Fe2O3 content, the random state of glass structure increases. The absorption bands of FTIR spectra become broaden and shift from the high frequency region to lower frequencies. With prolonging nucleation time and improving crystallization temperature, the strongest absorption bands also shift from the high frequency region to lower frequencies关键词
