WebbFTIR SPECTROSCOPY The structural order of kaolinites can be detected by differences in position and relative intensity of OH stretching and bending bands in IR spectrum (Madejová, 2003). The OH bands in kaolin typically display four sharp stretching bands between 3600 and 3700 cm-1 namely; 3697, 3670, 3652/50 and 3620 cm-1 Webb10 maj 2013 · The analysis of the metakaolin spectrum provides evidence that the conversion from kaolin to metakaolin was not complete, as the absorption bands at 3700 cm −1, in the –OH stretching region, and at 915 cm −1, ascribed to the bending vibrations of hydroxyl groups associated with Al cations in kaolinite , even if extremely broad, are …

Webb1 dec. 1990 · Single-crystal FTIR spectra of Keokuk kaolinite showed that rotation of the electric vector around the c/z axis in the ab plane of kaolinite resulted in a behavior … WebbThis modification affects the basal plane peaks. Further, thermal activation at 700 °C leads to dehydroxylation of the entire moisture content of kaolinite. However, the moisture contents of the mica quartz in the solid material remain unaltered. FTIR spectra reveal the emergence of another band at ∼820 cm −1. Webb17 apr. 2024 · Another focus area of the collected FTIR spectrum is the range of 800–1000 cm −1, where some differences between the various samples in the FTIR spectra were also observed. It appeared that the reference sand had no peak or shoulder within this range, but the dry received soil showed a very minor shoulder and the … physics of inhomogeneous inorganic materials
