Abstract

Material Ba1-xCaxFe12O19 (x = 0 - 1) telah berhasil disintesis melalui metode reaksi zat padat. Pada tahap pertama digunakan bahan berupa serbuk Fe2O3 (99.9 %), BaCO3(99 %) dan CaO (99 %) dilakukan proses pencampuran basah dengan High Energy Ball Mill selama 30 menit hingga diperoleh kondisi homogen. Pembentukan fasa magnet diperoleh dengan tahapan kalsinasi 750o C selama 1 jam dan optimal perlakuan panas pada 1100o C selama 5 jam terhadap padatan campuran serbuk. Analisis data difraksi sinar-x menunjukkan komposisi x = 0 - 0.9 didominasi fasa barium heksaferit. Sifat magnetik sesuai standar magnet ferit telah diperoleh dengan PERMAGRAPH. Tahap kedua digunakan Fe2O3 dari pasir besi dan CaO dari batu kapur. Hasil pengukuran sifat magnetik yang diperoleh sesuai standar magnet permanen. Hal ini menunjukkan bahwa material dari bahan alam dapat diaplikasikan sebagai magnet permanen. The material Ba1-xCaxFe12O19 (x = 0 - 1) has been successfully synthesized through solid reaction method. In the first step, the material of Fe2O3 powder (99.9%), BaCO3 (99%) and CaO (99%) was processed by wet mixing with High Energy Ball Mill for 30 minutes to obtain homogeneous condition. The formation of magnetic phase was obtained by calcination stage 750oC for 1 hour and optimum heat treatment at 1100oC for 5 hours against powder mixed solid. Analysis of x-ray diffraction data showed that the composition of x = 0 - 0.9 was dominated by barium hexaferrite phase. The magnetic properties of standard ferrite magnets have been obtained with PERMAGRAPH. The second stage is used Fe2O3 from iron sand and CaO from limestone. The result of measurement of magnetic properties obtained according to the standard of permanent magnet. This shows that the material of the natural material can be applied as a permanent magnet.
