12 X-ray Diffraction and Mineral Analysis – Mineralogy
12.5 Electromagnetic radiation. X-rays are a form of electromagnetic radiation (Figure 12.5). Whereas the wavelengths of visible light are 10 -7 to 10 -6 meters, X-ray wavelengths are only 10 -11 to 10 -8 meters. Long-wavelength X-rays grade into ultraviolet light; shorter wavelengths grade into cosmic and gamma rays.
XRD Mineralogy & XRF Analysis
X-ray diffraction is a direct minerology tool. It can offer qualitative mineral phase analysis, rough range concentration-wise, 2% – 100%. Other techniques can calculate or derive minerology, but XRD provides a direct minerology and this means that it identifies and quantifies the minerology directly from the crystal structure of your mineral ...
