Minerals | Free Full-Text | XRD Identification of Ore Minerals during
The on-board identification of ore minerals during a cruise is often postponed until long after the cruise is over. During the M127 cruise, 21 cores with deep-seafloor sediments were recovered in the Trans-Atlantic Geotraverse (TAG) field along the Mid Atlantic Ridge (MAR). Sediments were analyzed on-board for physicochemical …

XRD Mineralogy & XRF Analysis
X-ray diffraction is a direct minerology tool. It can offer qualitative mineral phase analysis, rough range concentration-wise, 2% – . 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.

The XRD pattern for bulk CdS, simulated from crystallographic data,5 is shown in Figure 1. The first three peaks in the CdS XRD pattern correspond to the (100), (002), and (101) planes of CdS, and these are highlighted in the wurtzite crystal structure in the inset to Figure 1. The higher index planes are also labeled on the XRD pattern.

Soil-plant potassium transfer: impact of plant activity on clay
Potassium (K) availability influences many processes in cultivated and natural ecosystems. Several studies suggest that "non-exchangeable" K+ ions fixed in 2:1 clay mineral interlayers contribute to plant nutrition. Although depletion of these K+ ions could be observed by X-ray diffractometry, this technique has never been considered for …

Quantitative Mineral Analysis by FTIR Spectroscopy
Traditionally, X-Ray diffraction (XRD) is used to identify minerals of oil well core samples [1]. The capability of XRD for quantitative analysis for minerals is limited to the minerals having good crystal structures. For the amorphous and low crystallite minerals, XRD cannot provide accurate quantitative information.

X-ray Powder Diffraction (XRD)
X-rays are generated in a cathode ray tube by heating a filament to produce electrons, accelerating the electrons toward a target by applying a voltage, and bombarding the target material with electrons. When electrons have sufficient energy to dislodge inner shell electrons of the target material, characteristic X-ray spectra are produced.
