Portland cement clinker mineral phase X-ray diffraction
Analytical method
Warning. The X-ray diffractometer used in this analysis method should have special radiation protection measures to avoid radiation leakage. The instrument manufacturer should
Ensure that the radiation dose of the X-ray diffractometer meets the requirements of the "Regulations on the Administration of Radioactive Devices and Ray Devices." X-rays are produced by high voltage
The peak value is as high as 55kV. When operating the X-diffractometer, you should always pay attention to safety to avoid serious electric shock to the operator.
1 Scope
This document specifies the principle of the X-ray diffraction analysis method for the mineral phase of Portland cement clinker, the calibration and quantitative analysis of the X-ray diffractometer
Confirmation of procedures, measurement procedures and reports.
This document is applicable to the determination of various mineral phases in Portland cement clinker (including alite (tricalcium silicate, C3S), belite (dicalcium silicate)
C2S), aluminate (tricalcium aluminate, C3A), iron aluminate (tetracalcium aluminate, C4AF)), it can also be used to determine periclase (magnesium oxide,
MgO), Glauber's salt (potassium sulfate, KS), hemihydrate gypsum (calcium sulfate hemihydrate, CS
2H2O
), anhydrous gypsum (calcium sulfate, CS) and calcite
(Calcium carbonate, CaCO3).

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
X-ray diffraction X-ray diffraction; XRD
X-rays are scattered by electrons in the crystal material, and the coherent scattered light appears as a result of interference enhancement in a specific direction.
Note. The diffraction pattern produced by each crystal reflects the distribution of atoms inside the crystal. Based on the Bragg equation, when a crystal is composed of elements, groups or knots
When there is a difference in structure, the diffraction spectrum will be shown in the number of diffraction peaks, angular position, relative intensity and diffraction peak shape. XRD patterns can be used as
Qualitative analysis and quantitative analysis basis of crystals.
3.2
Preferred orientation
The non-random orientation of the crystal grains relative to the sample surface.
Note. The preferred orientation leads to major changes in the intensity of some XRD lines, which is one of the sources of error in XRD analysis. The preferred orientation can be pulverized for a long time
Reduce the degree of orientation, but cannot eliminate it.
3.3
Reliabilityfactor
RWP
A parameter that reflects the degree of consistency between the overall fitted pattern and the measured XRD pattern.
