Abstract

An identification of magnetite nanoparticles synthesized from natural iron sand using co-precipitation method has been conducted. The treatment was undertaken at room temperature and the heating used a pair of acid-base compounds, namely HCL as a solvent and NH4OH as a precipitate. Crystal structures, percentages of elements, particle sizes and magnetic characteristics of the materials were characterized by testing XRF, XRD and Permagraph. The results were then compared with the commercial material purchased from Aldrich (with 97% purity). From the results, it was found that the percentage value of the purity of Fe3O4 derived from natural sand before the extraction was 81.42%, and after the extraction it increased to 86.73%. Furthermore, the saturation magnetization (Ms) value for Fe3O4 ferrite from iron sand was 0.29 T, the residual magnetization or Remanen (Br) was 0.081 T, and Coersivity (Hc) was 1.82 kA/m.

Highlights

Aceh is one of the provinces in Indonesia that has large natural resources
The reaction temperatures are ranging from room temperature to 100oC with the diameter of nanoparticles of 2 to 51 nm [5]
The materials in this study consisted of main material of pure magnetite Fe3O4 (97%, size 50100 nm, Aldrich sigma production) and Fe3O4 iron oxide powder from iron sand collected from Syiah Kuala beach in Aceh

Summary

INTRODUCTION

Aceh is one of the provinces in Indonesia that has large natural resources. There are abundant natural resources and important natural materials in Aceh such as gold, coal, iron ore, iron sand and so on. The natural resources are still in raw form and most of them have not been found and the deposits are unknown. Along with the development of industry, it automatically increases the demand of certain raw materials for certain products. The co-precipitation method is the simplest method because the treatment process is easier to do and requires a low reaction temperature (
