Phase-targeted X-ray diffraction
A powder X-ray diffraction (XRD) method to enhance the signal of a specific crystalline phase within a mixture is presented for the first time. Specificity to the targeted phase relies on finding coincidences in the ratios of crystal d spacings and the ratios of elemental characteristic X-ray energies. Such coincidences can be exploited so that the two crystal planes diffract through the same s...
متن کاملDetermination of cristobalite phase content in ceramic cores using various X-ray quantitative phase analysis methods
The aim of this research is to investigate different X-ray based quantitative phase analysis methods for determination of cristobalite phase content in ceramic cores. For this purpose, four popular routes including peak absolute intensity method, relative intensity ratio method, direct or calibration method and internal standard (or Alexander-Klug) method have been chosen. Some control samples ...
متن کاملX-Ray Diffraction and X-Ray Absorption Spectrocopic Analyses for the Ruthenium Perovskites
According to the Rietveld refinements and X-ray absorption studies at the Ru K-edge, it is found that three compounds La2BRuOg (B=Li, Mg, and Zn) are monoclinic with space group of P21/n, and that the mthenium ions with two oxidation states +IV (d4) and +~(d3) are stabilized in an octahedral site of oxide lattices. A correlation is obtained between absorption edge position and the oxidation sta...
متن کاملIntroducing an Optimized Method for Obtaining X-ray Diffraction Patterns of Biological Tissues
Introduction Individual X-Ray diffraction patterns of biological tissues are obtained via interference of coherent scattering with their electrons. Many scientists have distinguished normal and cancerous breast tissue, bone density, and urinary stone types using the X-Ray diffraction patterns resulting from coherent scattering. The goal of this study was to introduce an optimized method for obt...
متن کاملX-ray Diffraction and SEM Studies on the Effect of Temperature on the Formation of Main Phase Sr2MgSi2O7 Using a Wet and Dry Method for its Preparation
A pure Silicate host namely Sr2MgSi2O7 as a support for a long-lasting afterglow when dopped with rare-earth elements was sought after. To this end the process of obtaining firing temperatures of the above mentioned phase in normal condition was carried out using suggested wet and dry methods. The degree of purity obtained in these preparatory methods as wel...
