Abstract

Barium M-hexaferrite (BaFe12O19) as an absorber of microwaves has been synthesized by coprecipitation method and its effect on changes in temperature and dopant substitution has been characterized. Basic materials used in the synthesis to are BaCO3, FeCl3.6H2O, HCl, NH4OH and nickel metal. The process of synthesis of barium M-hexaferrites and FTIR characterization performed at the Analytical Chemistry Laboratory of the Faculty of Mathematics and Natural Science Unram, characterization by XRD, SEM, TEM, LCR meter at LIPI Physics and characterization by VSM in BATAN. This study used a variation of calcination temperature of 80, 400, 600 and 800°C for 4 hours with a variety of dopants 0; 0.4; 0.7 and 0.9.The experimental results showed that a single phase is formed and a uniform distribution on M-barium hexaferrites (BaFe12-xNixO19) at 800°C calcination temperature and variations in dopant x = 0.7 was observed. Constituen elements of barium M-hexaferrites spread evenly according to the concentration of each element in the compound BaFe12-xNixO19. The addition of the dopant concentration can increase the value of conductivity that is in the range of 10-6 S/cm to 10-4 S/cm included in the semiconductor material. While the value of coercivity at x = 0.7 and calcination temperature of 800°C at 0.05 T and magnetization value of 2.25 emu / g that is softmagnetic.
