Minimization of Preferred Orientation in Powders by Spray Drying

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


The spray drying of powders is a method of forming spherical or torroidal shaped agglomerates. A relatively simple method is given for preparing spray dried samples of the quantities used in x-ray diffraction analysis. This technique is shown to minimize preferred orientation effects on diffraction intensities from materials of widely differing symmetry and crystallite habit.
