Low Temperature Analysis of Kaolin Clay Using Diffuse Reflectance

September 01, 2012

Clays, like kaolinite and smectite, are hygroscopic and it is well known that the adsorbed water can be driven off at elevated temperatures. At very low temperatures, in addition to the typical band narrowing and shifting, changes in the O-H bond vibrational modes of clays have also been observed.
