“…The big interest in silicon and various uses of silica made silica deposits that have good specifications and a considerable amount of quartz content of great importance, and this led it to be the aim of many researchers around the world that dealt with the characterization of sand in those deposits and study the physicochemical properties and its structural composition, generally or according to subsequent use.

A spectroscopic, physiochemical, and radioactivity characterization of quartz sand samples from Al Qaryatyien area in Syria has been carried out. XRF analysis showed the dominance of SiO2 in the chemical composition of the sand (95.10% on average) with a tiny portion of other minerals. The index of XRD spectrum revealed the quartz structural for SiO2 in the sand where the calculated unit constants (acal=4.9070, ccal=5.3539) were so close to those found in the references (aref=4.91120, cref=5.4040), which refer to a high degree of purity. Moreover, the good crystallinity of quartz was confirmed by FTIR analysis where the calculated crystal Index was (CIcal=1.415). Thermal analysis manifested the stability of the sample almost, the TGA curve indicated slight changes in mass (1.45%), and most of those changes were due to losing both moisture and crystalized water. The DTA curve showed stability in slope with no changes except the characteristic endothermic peak of the phase transition of quartz from α to β. On the other hand, the natural radioactivity of the decay chains of 238U, 232Th, and 235U was measured using HPGe spectrometry and the mean values of radionuclide activity concentrations were below the limit of detection.
