Morphological characteristics and electrical properties analysis of silica based on river and coastal iron sand

This study aims to analyze silica's morphological characteristics and electrical properties based on the river coastal sand. Iron samples were taken from Sompang sand, East Lombok Coastal Sand Gading, Mataram City. The silica was synthesized using sol-gel method with a sintering temperature variation of 100 175 ℃. Morphological analysis done SEM-EDX. iron sand included measuring dielectric constant parallel plate method. Furthermore, resistivity measured two-point probe In silica-based sample, value inversely proportional temperature. contrast, sample directly Silica-based has about 7.1'104 Wm at 100℃ 3.5'104 175℃. 1.8'104 research is preliminary natural sand-based improve understanding physical be used in technological applications, such as sensors. However, 1.02'102 1.18'102 1.97'102 1.15'102
