Abstract


Telah dilakukan penelitian mengenai pengaruh variasi pH pelarut HCl pada sintesis barium M-heksaferrit dengan doping Zn (BaFe11,4Zn0,6O19) menggunakan metode kopresipitasi. Metode kopresipitasi sederhana dilakukan untuk mensintesis serbuk barium M-heksaferrit BaFe11,4Zn0,6O19. Eksperimen dilakukan dengan mengontrol pH HCl dengan variasi nilai  pH= 1; 2; 3; 4 dan dilakukan  drying dengan  T=80⁰C dan dikalsinasi pada T=150⁰C. Proses heat treatmant tersebut di  holding time  selama 4 jam. Serbuk barium M-heksaferrit BaFe11,4Zn0,6O19 dikarakterisasi dengan DSC/TGA, XRD, SEM, dan VSM. Fasa barium M-hexaferrite BaFe11,4Zn0,6O19 terbesar terdapat pada nilai pH=1 pada temperatur kalsinasi 150 ⁰C selama 4 jam sebesar 83,98% mempunyai nilai koersivitas (Hc) sebesar 0,0178T, magnetisasi remanensi sebesar 3,113 emu/gram dan magnetisasi saturasi (Ms) maksimum sebesar 25,50 emu/gram. Gambaran foto SEM –EDX dari prekursor BaFe11,4Zn0,6O19 pada temperatur kalsinasi 1500C memperlihatkan bahwa elemen dari barium M-heksaferrit adalah Ba, Fe, Zn, O dan ukuran partikelnya adalah 1 µm serta ukuran kristal adalah 38,202nm.
