Struktur Kristal Dan Morfologi Permukaan – Sintesis Sno2 Menggunakan Metode Sol-Gel

Abstract

SnO2 oxide powder was synthesized using the sol-gel method. SnO2 oxide powder was produced using a solution of tin(IV) chloride (SnCl4) and 25% ammonia (NH4(OH)) by annealing the final product for 4 hours at 900 °C. The pH variation was carried out at pH 7 and 9. XRD analysis showed that the structure of SnO2 formed was polycrystalline with a tetragonal crystal structure with crystal planes (110), (101); (200), (111), (210), (211), (220), (002), (310), (112), (301), (202), (321), (400), (222 ), (330) wherein the crystal plane (110) has the predominant structure. The crystal size using the Scherrer formula, varied from 56,204 and 54,936 nm for pH values ​​7 and 9. The size using HSP analysis, in the (110) plane the values ​​obtained were 561,594 and 543,901Å for pH 7 and 9. The crystal size decreased with increasing pH. Surface morphology was carried out by SEM analysis, obtained grain sizes of 71.5 and 62.32 nm at pH 7 and 9, respectively. The variation in pH mostly affected the size, shape, and morphology of SnO2.

Application of MLR Method and Pearson Correlation on Nickel Extraction from Laterite Using Nitric Acid

“…Previous study investigated the study of provskite micro oxide structure of an electrochemical cathode at 1000 o C and 1100 o C (Subardi, 2022). On other occasion, XRD analysis was applied to investigate the surface of SnO2 crystalline synthesis by sol gel process (Arini et al, 2022). Figure 5 shows the XRD presentation of laterite mineral after roasting (600 o C, 1h).…”
