Any idea about peak identification of non-expandable minerals in EG treated oriented mounts?

09 January 2019 1 7K Report

During XRD analyses of oriented clay mounts, a number of peaks which are NOT typical of expandable clay minerals have been observed on XRD patterns of EG solvated ones. Ethylene Gycol was provided by MERK. It looks that some sort of crystalline phase(s) has been generated which was disappeared due to heat treatment (550 oC). Anybody has any idea about it?
