Sažetak

The paper deals with the influence of particle size in quantitative
X-ray analysis of substances with a pronounced disposition
of crystallites to orient prefe rentially. Dep endence of the broadening
of diffraction maxima on the degree of preferential orientation
of crystallites is proved experimentally. An equation has been
derived to correct the broadening of diffraction maxima to the
value belonging to randomly oriented specimen. Such a correction
is needed to find out the dependence of the coefficient of proportionality
a (reflectio n intensity/weight fraction) on the particle
size of c rystallites . This dependence is expressed by equation
B 1 • u. = cons t. which is the result of experiments carried out in
quantitative X-ray analysis of calcium hydroxide.
