Rietveld-based methods
International Tables for Crystallography (2019). Vol. H, Section 3.9.4.5, pp. 352-353 [ doi:10.1107/97809553602060000954 ]
... . In this case, the value for the instrument constant, K, can be derived using the Rietveld scale factor, ZMV and ... an arbitrary value of unity for both the determination of K and all subsequent analyses, since the overall chemical content of ... the `instrument configuration'. This requires a modification of the K value and subsequent calculation of concentration to compensate for ...
Matrix flushing
International Tables for Crystallography (2019). Vol. H, Section 3.9.4.4, pp. 351-352 [ doi:10.1107/97809553602060000954 ]
Matrix flushing 3.9.4.4. Matrix flushing Once the correct value of RIR is determined for each phase, the matrix-flushing method can be applied using equation (3.9.15) . For fluorite in sample 1D, the calculation proceeds as follows: compared with a value of 0.5358 added to the sample by weight. Fig. 3.9.4 ...
Reference intensity ratio
International Tables for Crystallography (2019). Vol. H, Section 3.9.4.3, p. 351 [ doi:10.1107/97809553602060000954 ]
Reference intensity ratio 3.9.4.3. Reference intensity ratio For this exercise, the peak intensities and phase concentrations in Tables 3.9.1 and 3.9.2 for sample 1H can be used to determine the RIRs for fluorite and zincite. These RIRs should be compared with reported values for fluorite in the ICDD database (ICDD, 2015 ...
Internal standard method
International Tables for Crystallography (2019). Vol. H, Section 3.9.4.2, pp. 350-351 [ doi:10.1107/97809553602060000954 ]
Internal standard method 3.9.4.2. Internal standard method Application of the internal standard method normally requires the addition of an appropriate phase in known amount to each sample to be analysed. In order to use this data for demonstration of the internal standard method, it is necessary to designate one of the ...
Absorption-diffraction method
International Tables for Crystallography (2019). Vol. H, Section 3.9.4.1, p. 350 [ doi:10.1107/97809553602060000954 ]
Absorption-diffraction method 3.9.4.1. Absorption-diffraction method In this method, the QPA of each phase is conducted independently of the others. For each phase, the determination of a specific calibration constant, C, was achieved using a rearranged equation (3.9.3) . The sample where the relevant phase was present at about 55wt ...
Demonstration of methods
International Tables for Crystallography (2019). Vol. H, Section 3.9.4, pp. 350-353 [ doi:10.1107/97809553602060000954 ]
... A curved graphite post-diffraction monochromator was fitted to eliminate K[beta] radiation. Data were collected from 15 to 145° 2 ... .
