Characterization of Strontium Ferrite Based on Natural Iron Sand at Banjar Beach with Co and Zn Ion Doping as Generator Material Electricity

This research aims to determine the characteristics of strontium-based on ferrite natural iron sand doped with Co and Zn ions as an electric generator driver. Iron sand contains minerals such as magnetite (Fe3O4), hematite (α-Fe2O4), and maghemite (γ-Fe2O3) which can be used to making permanent magnets. The method used is coprecipitation to produce nano-sized magnetite minerals which are used as a basic material in permanent magnets production. In order to increase the magnetic and electrical properties, Co and Zn doping is added with several concentrations (x = 0.0; 0.5; 1.0). The final result is a sample powder that has been heated at a temperature of 80 ˚C for 24 hours. More higher the calcination temperature used, made more darker result sample color. The FT-IR test results show the presence of O-H, Sr-O, Co-O, Zn-O, and Fe-O compounds at certain wavelengths ranging from 400-690 cm-1.
