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

This study aims to synthesize barium M-hexaferite using the coprecipitation method with Zn doping based on natural iron sand at Tebing Beach of North Lombok as a microwave absorbent material. used 3 variations concentration (x), namely x = 0.000; 0.400; and 0.800. In addition, in calcination temperature were also carried out, 400°C 1100°C. After stage, sample is ground obtain smaller or nano-sized particles. The results showed that has brick red color for black shows higher temperature, darker sample.
