Abstract

Sinlesis multiferoik BiFeO3 didoping Pb telah dilakukan dengan metode liquid mixing, menggunakan Fe mumi dan Fei03 hasil sinlesis dari pasir besi. Dalam penelitian ini digunakan variasi konsentrasi doping Pb x - 0,25; x=0,5; variasi suhu kolsinasi dan variasi holding time. Hasil sintesis dikorakterisasi dengan XRD (X-ray Difraction) dan magnetic susceptibility balance. Sampe/ dengan variasi konsentrasi doping Pb x=0,25 ditemukon fasa pengotor BFO selcunder sedangkon sampel dengan x - 0,5 ditemukan fasa pengotor BFO sekunder dan fasa bahan penyusun. Dekomposisi fasa BiFeO3 menjadi fasa sekunder BFO meningkot dengan meningkotnya suhu kolsinasi dan holding time. Doping Pb memperbesar kemungkinan terbentuJcnya fasa BiFeO3• Konsentrasi doping Pb x=0,5 dapat meningkotkan prosentasefraksi volume BiFeO3 sebesar ~7% dan dapat menunmkon prosentase fraksi volume fasa BFO selcunder sebesar ~15%, namun dekomposisi fasa menjadi fasa bahan penyusun meningkot sebesar ~43%. Ukuran kristal BiFeO3 hasil sintesis berkisar ~29 nm hingga ~112 nm. Sampe/juga memi/ild nilai X berkisar 1,69xl0-7_ ============================================================================================== Synthesi of multifferoic BiFeO3 doped with Ph has been done by the liquid mixing method, using pure Fe and Fe2O3 synthesized from iron sands. In this study it was used a variation of Pb concentration of x=0.25; x =0.5; varying heating temperature and holding time. Synthesized samples were characterized by XRD (X-ray Diffraction) and magnetic susceptibility balance. Samples withx = 0.25 was found to have BFO secondary impurity phase, while the samples with x have BFO secondary impurity phases and constituent materials phase. Decomposition phase BiFe03 into the BFO secondary phase increases with increasing calcination temperature and holding time. Doping of Pb has led to increasing phase formation of BiFe03. Samples with x=0.5 show an increase of volume fraction of BiFeO3 by -7% and surpress BFO secondary phase by -15%, but the phase decomposition of constituent materials increases by -43%. Synthesized BiFe03 has crystal size ranging from -29 nm to -112 nm, and magnetic susceptibility x value around 1.69 x10'
