Powder diffraction analysis is generally considered information poor compared to single-crystal analysis, say Dinnebier, Leineweber, and Evans, but in fact the information content of a powder pattern is huge, but sophisticated analysis methods are often needed to harvest the maximum amount of information from the data.
The team examined more than 200 Cambrian rock samples using powder X-ray diffraction analysis to determine their mineralogical composition, comparing rocks with Burgess Shale-type fossils with those with only fossilised shells and bones.
The results are analyzed in accordance with "X-ray diffraction analysis of the relative content of clay minerals in sedimentary rocks" and "X-ray diffraction quantitative analysis of the clay mineral aggregate and common nonclay minerals in sedimentary rocks" [23, 24].
(2) X-ray diffraction analysis: The core-drilling machine was used to drill the specimens which were cured in curing room for 90d, and the powder obtained should be passed through the standard square hole stone sieve of 0.3mm.
At the end of this process, colourless crystals appropriate for single crystal X-ray diffraction analysis were obtained with a yield of 60%.
In orderto explain physical-ceramic characterization results, an X-ray diffraction analysis was performed on some of the fired materials.
The heat treated glass-ceramics samples were tested by X-ray diffraction analysis of the powder crystalline samples to identify the crystalline phases developed by crystallization of the glass.
To determine the phase composition of ammonium powders of tetravanadate and vanadium oxides, an X-ray diffraction analysis performed on the DRON-3 installation in monochromatized copper radiation of CuKa was used.
Petrographic and mineralogical assessment carried out by microscopic study and X-ray diffraction analysis revealed that, these rocks show mild to light alteration in the form of serpentinization.
The X-ray Diffraction Analysis authenticated the pozzolanic reactivity of produced waste paper sludge and confirmed the outcome of Strength Activity Index.
