In order to determine quantity of clinker minerals and raw materials in clinker, internal standard technic of X-ray diffraction was examined. The cement clinkers prepared from mixture of lime, quartz and alumina were burned at temperature from 1,000℃ to 1,600℃ for one hour every 100℃. Using calibration curves prepared from mixture of fluorite and synthetic clinker minerals, lime, quartz, tridymite tricalcium aluminate, wollastonite, βB-lite, γB-lite and A-lite in the clinkers was determined. On the other hand, quantity of lime, quartz and βB-lite was checked up by other methods. The result obtained from the X-ray analysis was generally equal to the data from other methods. It may be concluded that X-ray diffraction analysis is successfully applied to determine the quantity of clinker minerals and raw materials in clinker, and also is usefull for study of chemical reaction between raw materials during cement burning.
