Penerapan Metode Sol-Gel dengan Variasi Temperatur dan Waktu Kalsinasi pada Sintesis Barium M-Heksaferit (BaFe12O19) Idon Joni, Darminto

Abstract

Synthesis of Barium M-Heksaferit (BaFe12O19) was conducted by sol-gel method. The precursors resulted from the sol-gel process was calcinated at 600-1000⁰ C for 3, 4, dan 5 hours. Phase purity examination using XRD dan Rietica software has given result BaFe12O19 content of 64.9%. The prepared powders have the saturated magnetisation of 15.97 emu/gr, coercivity of 0.35 tesla and remanent magnetisation of 9.46 emu/gr according to measurement using VSM.
