Abstract
Abstract Synthesis of BaFe 12 O 19 based on natural iron sand with Cu and Ni doping using the coprecipitation method has been done. This research was conductedat the Chemistry Laboratory, Faculty of Teacher Training and Education, Mataram University. The synthesis was carried out through the variation of doping ions and calcination temperature. The concentration of doping ion used is x = 0.0; 0.4; 0.8; and 1.0 with variations in calcination temperature of 200, 600, and 1000 0 C. The materials used are BaCO 3 , Fe 3 O 4 , CuSO 4 , and NiCl 2 .6H 2 O powder. This synthesis process aims to obtain BaFe 12-2x Cu x Ni x O 19 powder that will later be used as a microwave absorbent material. To obtain sample powder of BaFe 12-2x Cu x Ni x O 19 , thisresearch is carried out through three stages: natural sand separation, magnetic minerals separation, and synthesisand calcination. The separation is to attach magnetic materials from the sand using a permanent magnet. After that, the magnetic mineral is detached from the separated sand to obtain Fe 3 O 4 powder, which will later be used for synthesis. The results of synthesis and calcination showed that the more doping ions applied, the more concentrated the resulting powder. Similarly, according to the temperature variation, the higher the temperature, the more black the sample powder is.
