QUANTITATIVE X-RAY DIFFRACTION ANALYSIS

A GENERAL THEORY OF QUANTITATIVE X-RAY ANALYSIS IS DERIVED AND USED TO SUGGEST SEVERAL PROCEDURES. THE NEED FOR CALIBRATION CURVES SOMETIMES CAN BE ELIMINATED; LINES MAY BE USED EVEN THOUGH THERE MAY BE SUPERPOSITIONS; SEVERAL COMPONENTS MAY BE DETERMINED SIMULTANEOUSLY. THE THEORY IS APPLIED TO THE DETERMINATION OF CALCIUM HYDROXIDE USING MAGNESIUM HYDROXIDE AS THE INTERNAL STANDARD. SAMPLES CONTAINING CALCIUM HYDROXIDE IN THE PRESENCE OF HYDRATED CALCIUM SILICATES HAVE BEEN ANALYZED. LIMITS OF ERROR ARE DISCUSSED. PRECAUTIONS ARE NECESSARY BECAUSE OF THE CARBONATION OF EXPOSED SAMPLES. /PCA/
