AB  - The synthesis of SBA-15 material with spherical particles is performed by the template method by using only a surfactant Pluronic P123 under acidic conditions. In the synthesis of SBA-15 with spherical particles, an HCl solution was used after specialised chemical treatment of clay purification. The dominant presence of the spheres with diameters up to around 2 μm was confirmed by the scanning electron microscopy(SEM) method. In contrast, the Energy-dispersive X-ray spectroscopy(EDS) confirmed that the spheres consisted only of SiO2 in composition. In addition to the methods mentioned above, X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy(FTIR) methods were used to characterise SBA- 15 materials. Application of HCl solution after chemical treatment of clay purification represents the application of technology in the synthesis of spherical SBA-15.

AB  - The clay minerals deposit from the mining basin Kolubara, Serbia, is a natural sediment material with high economic potential in many fields. The chemical composition of starting clay determined by inductively coupled plasma spectrometry shows that its main composition of SiO2 is 88.00 wt.%. Organic impurities from clay have been removed by heat treatment at 600 °C for 2 h in air. After thermal treatment, an aqueous solution of HCl sedimentary mineral was chemically treated. Surface properties of starting clay and thermally and chemically treated clay (treated clay) were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and particle size distribution method. The XRD analyses of the starting and treated clay confirmed that quartz is a significant phase, followed by the appearance of feldspar and smectite clays. The SEM method showed impressively layered microstructure on various magnifications for both groups of investigated materials. The average particle diameter value for starting clay was about 23 μm and about 53 μm for treated clay. These methods showed that the starting clay changed the surface properties during thermal and chemical treatment, resulting in the merging of clay layers.
