X-ray Diffraction in the Petrochemical Industry

Identification of Swelling Clays with the D2 PHASER

The D2 PHASER is a mobile benchtop X-ray diffractometer (XRD) used in the identification of both bulk and clay minerals within geological samples.


In this report, we describe the analysis of clay samples using oriented mounts. Diffraction studies enable the differentiation between swelling and non-swelling clays by observing the shifting of diffraction peaks due to expansion in swelling clays.
