Abstract:
An x-ray diffraction apparatus comprising:measuring means including an optical system with a measured-data-obtaining divergence slit for making x-rays incident on a sample through said measured-data-obtaining divergence slit, measuring intensity of diffracted x-rays by said sample, and thereby providing, as measured data, ratios between intensity values of said diffracted x-rays at different angles of diffraction; reference data storing means for storing, as reference data, ratios between intensity values of x-rays made incidence on various reference materials through a reference-data-obtaining divergence slit and diffracted therefrom at different angles of diffraction; data correcting means for correcting at least either of data selected from the group consisting of said measured data and said reference data so as to thereby eliminate effects of difference between x-ray intensities made incident on said sample through said measured-data-obtaining divergence slit and on said reference materials through said reference-data-obtaining divergence slit; and qualitative analysis means for carrying out qualitative analysis of said sample by comparing said measured data and said reference data after corrections are made by said data correcting means.
