![]() ![]() X-ray diffraction is the principle method of characterization and its simplicity and advantages of the powder diffraction technique can help to identify the unknown material after comparing with the diffraction spectrum of the specimen material provided by the Joint Committee for Powder Diffraction File (JCPDF) inbuilt in the software and licensed. Very small changes in the X-ray powder diffraction pattern may appear as a new peak(s) or shoulders or shifts in the peak position due to impurity of the solid sample or some other well-defined crystalline material adhered with the very high percentage of the solid sample can imply the presence of a new form of crystal components. Indeed the morphology of a stone can even induce to adopt the X-ray diffraction technique in identification of unknown solid samples. High-resolution PXRD patterns provide good data to determine the phase composition of crystalline samples, yet morphology and particle shape/size can induce severe preferential orientation that can degrade the utility of XRD powder data. Powder X-ray Diffraction (PXRD) is a decisive tool in identifying polycrystalline materials by their unique diffraction patterns and is one of the best common analytical methods for nondestructive technique which provides information on structures, phases, texture, and other structural parameters of grain size, crystallinity, strain for characterizing crystalline materials about the composition of the solid crystalline material and are especially significant for the analysis of solid materials in forensic science for the forensic identification of unknown solid. Precious stone instead it is a category of mineral deposition, PbS, Galena. This study reveals that the stone is not a category of The diffraction spectrum hasīeen measured with the proportional counter in the 2° to 100° range at room Using Philips, DY993 X-ray Powder Diffractometer. Make-up of unknown materials, and has also been employed Techniques in identification of minerals to examine the physico-chemical Of unknown stone, Powder X-ray diffraction (PXRD) is one of the primary Transparency, cleavage, streak and other associated minerals for identification Physical and optical parameters measured such as specific gravity, hardness, luster, Raw or ingredients for making a powerful bomb or otherwise. Pinpoint whether the stone is in a category of gemstone, radioactive elements, A dark and lead to silver grey soft irregular-shaped with heavy weight stone has been analysed asĪ part of research work for determining the components of the stone thereby
