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'
