Extract

X-ray diffraction has been shown to provide an accurate qualitative and quantitative determination of the pigment composition of paint films. This analysis, however, is frequently complicated by the presence of pigments with plate-like crystallites which show a marked tendency to orient in preferred directions in drying paint films. The variability in the degree of orientation causes line intensity variations not attributable to pigment concentration.

A technique based on a summation of the intensities of many lines has been used to correct for the effects of preferred orientation in the analysis of retained austenite in certain steels. This method is shown to be applicable to the quantitative analysis of mica in paint films.
