Sifat Magnetik Dan Struktur Partikel Dari Pasir Alam Desa Logas Kabupaten Kuantan Singingi Di Doping Menggunakan Ion Cobalt

---

Determination of magnetic properties and structural properties of natural sand from Logas Village, Kuantan Singingi have been carried out using a magnetic Probe Pasco PS-2162 and X-Ray Diffraction method. Two types of samples were synthesized using a multi step ball milling method for 90 hours and 90+30 hours. The product of the multi step ball milling was doped using Cobalt ions (Co(NO3)2.6H2O). Results showed that the magnetic suceptibility increased with increasing of ball milling time, from 90 hours to 90+30 hours and increased again after doped with Cobalt ions for 20 hour. This resulted magnetic suceptibilies are within the interval of (46-80000) x 10-8 m3/kg which are the interval of Ilminite mineral (FeTiO3; Antiferromagnetic). X-Ray Fluorescence result shows that the composition of Fe and Ti increases after milled for 90+30 hours, while other element like Si decrease. The XRD result confirms that the phase of the sample structure is Hematite (α-Fe2O3). However, some other phases including SiO2 and FeTiO3 are observed in diffraction pattern. This indicates that the sample is not purely hematite. The phases are clearly shown in XRD result patterns.

Key words : natural sand, ball milling, magnetic suceptibility and doping.
