3 Principle of the method
When X-rays illuminate the crystalline material, diffraction will occur, and each crystalline material has its own specific diffraction characteristics. Under certain conditions,
The intensity of diffraction produced by a substance in a mixed substance is proportional to the content. Measuring the intensity of the diffraction line, when the measured substance and the known content are referenced
After the intensity of the diffraction line of the substance is determined, the measured substance can be quantitatively analyzed.
4 reagents and materials
