Determination of X- ray diffraction of titanium dioxide pigment Anatase and rutile ratio

1 Scope

This standard specifies the method for the determination by X- ray diffraction of titanium dioxide pigment in anatase and rutile ratio. This standard applies to the determination of titanium dioxide pigment in anatase and rutile ratio. The method may also be used containing titanium dioxide pigment The mixture, dry coating, liquid paint and powder coating. A method of this standard apply to be free of interferences or interferences can be removed (see Appendix A) of any sample; B method is suitable for the sample In all phases of qualitative accurate, and that any data sample crystal structure of these phases can be obtained.

2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. GB/T 3186 Paints, varnishes and raw materials for paints and varnishes - Sampling Principle 3 3.1 A standard method using the intensity ratio method, as measured from anatase and maximum diffraction peak intensity with X- ray diffraction rutile will Diffraction peak intensity of anatase is converted into rutile with respect to the content of anatase, rutile content is determined by the difference. 3.2 Standard B method using the Rietveld analysis lawful, that is based on the crystal structure and structural parameters of the model assumptions, combined with a Species peak shape function to calculate the polycrystalline diffraction, adjust these structural parameters and peak shape parameters make computing spectrum consistent with the experimental determination of the spectrum obtained Structural parameters and peak shape parameters, and thus the determination of titanium dioxide pigment in anatase and rutile ratio.

4 instruments and experimental conditions

4.1 X- ray diffractometer Comprehensive diffractometer stability better than 1%. NOTE. Integrated stability of this standard instrument refers to the same conditions on the same test the same diffraction surface of the sample, measured once every 10min diffraction intensity in Diffraction line intensity values \u200b\u200bmeasured within 8h relative standard deviation σ-1 (see YB/T 5320-2006). 4.2 Test Conditions 1) 4.2.1 High Voltage Power Supply Signal intensity select X- ray tube voltage, current, and other conditions, so 0.1% is anatase produced at least four times the noise strength. 1) In the case to ensure accuracy, but also to choose the best test conditions depending on the X- ray diffraction performance and test sample of the actual situation.
