The Effects of Porosity in Powder Diffraction,

Abstract

A direct measure of the effect of porosity on powder diffraction intensities can be obtained by measuring the ratio of the x-ray scattering from a porous, amphorphous material vs. its non-porous counterpart. The amorphous specimen eliminates the effects of extinction and preferred orientation inherent in diffraction from crystalline samples. Measurements on glass powders of controlled particle size vs. solid specimens were used to obtain porosity corrections for scattering angles 10 degrees < meta < 80 degrees and for particle sizes in the range mu(t) = 1.0 to mu(t) = 3.2.
