Synthesis BaFe₁₂O₁₉ based on natural iron sand with Cu and Ni doping using coprecipitation method

Abstract

Synthesis of BaFe12O19 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 0C. The materials used are BaCO3, Fe3O4, CuSO4, and NiCl2.6H2O powder. This synthesis process aims to obtain BaFe12-2xCuxNixO19 powder that will later be used as a microwave absorbent material. To obtain sample powder of BaFe12-2xCuxNixO19, 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 Fe3O4 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.

Synthesis of Barium M-Hexaferrite Using Co-precipitation Method with Zn Doping Based on Natural Iron Sand at Tebing Beach, North Lombok as Microwave Absorbent Material

“…Indonesia is a country with abundant natural resources, one of which is natural iron sand (Susilawati et al, 2021). Iron sand is a source of natural magnetic material that can be obtained along the coastline (Elinda et al, 2022;Rahmawati et al, 2013;. Lombok Island has a coastline of 2,333 km, this certainly makes Lombok Island's iron sand a potential for development, one of which is at the Tebing Beach of North Lombok .…”

Analysis Magnetic Mineral Content of Natural Iron Sand in Beach Island Lombok as Basic Materials of Micro Wave Absorbers

“…The difference in the sand is spread throughout the island, starting from the dark in the northern part of the island, to white in the southern part (Doyan et al, 2020). Coastal sand is often found in the coastal area of the island, but its processing is still rarely used in the field of infrastructure development because it has the characteristics of grains that are fine and rounded, have a large grain, and contain salt (Elinda et al, 2022).…”
