The work deals with the problem of preferential orientation
of crystallites in quantitafrwe X-ray analysis. A n ew method has
been worked out theoretically. and practically for the correction
of reflection intensities from \u27polycrystalline samples w ith preferentially
oriented crystallites. Equations are included for the
determination of correction parameters. Practical a pplication of
the new method is demonstrated on quantitative X-ray analysis of
calcium hydroxide. The work includes a calibration graph for the
determination of coefficient a, comparing corrected and uncorrecte
d values of analytical intensities of Ca(OH)2
