Abstract

Telah dilakukan penelitian tentang karakterisasi suseptibiltas magnet barium ferit yang disintesis dari pasir besi dan barium karbonat menggunakan metode metalurgi serbuk. Pasir besi diperoleh dari Sungai Sukam, Kabupaten Sijunjung, Sumatera Barat. Magnet barium ferit dibuat dengan mencampurkan Fe2O3 hasil oksidasi magnetit pasir besi dan BaCO3. Kemudian campuran tersebut dikalsinasi pada suhu 1000 oC, lalu dikompaksi dan kemudian disintering pada temperatur 1000 oC. Karakterisasi magnet barium ferit dilakukan dengan mengukur suseptibilitas magnetik menggunakan Bartington MS2 Magnetic susceptibility meter. Hasil penelitian ini menunjukkan nilai suseptibilitas yang diperoleh dari enam variasi persentase massa yaitu 5, 10, 15, 20, 25 dan 30% berturut-turut adalah 262,6×10-8, 438,0×10-8, 516,1×10-8, 549,9×10-8, 422,8×10-8dan 429,9×10-8 m3/kg. Dengan nilai suseptibilitas tertinggi pada persentase massa 20% sebesar 549,9×10-8 m3/kg. Tingginya nilai suseptibilitas dikarenakan ion Fe3+ yang seimbang pada komposisi barium ferit. Nilai suseptibilitas magnetik barium ferit naik dengan kenaikan persentase massa BaCO3 5 hingga 20%, dan menurun untuk persentase massa BaCO3 besar dari 20%.
