Quantitative Phase Analysis of Devonian Shales by Computer Controlled X-Ray Diffraction of Spray Dried Samples

  • Steven T. Smith (a1), Robert L. Snyder (a1) and W. E. Brownell (a1)


Spray drying is shown to be an effective and rapid method for preparing samples for quantitative analysis by x-ray powder diffraction. Previously intractable problems like the simultaneous analysis of multiple phases in orientation prone systems can be carried out. Using this method, and a computer controlled diffractometer, five and six phase analyses of Devonian shales can be accomplished in approximately forty minutes. A rapid and convenient method for using the absorption diffraction technique for x-ray quantitative analysis is described.
