Abstract
Telah disintesis nanokristal superkonduktor Bi2Sr2Ca2Cu30iof8
dan Bii 6Pbo 4Sr2Ca2Cu30iof8 dengan metode kopresipitasi dan
pencampuran basah. Sesuai dengan analisis XRD, pembentukan
fasa 2223 lebih baik dengan metode pencampuran basah daripada
kopresipitasi, hasilnya fraksi volume fasa 2223 tanpa Pb dan
doping Pb berturut-turut mencapai 85,80% and 87,57%, setelah
sintering pada 840°C selama 8x1jam. Sampel secara bersamaan
memiliki Tc = 79,6 K dan 98,3 K; dan ukuran kristal 170,30 nm,
216,47 nm. Sampel juga menunjukkan gejala ferromagnetik
untuk fasa 2223 tanpa Pb sedangkan yang doping Pb bersifat
paramagnetik.

Superconducting Bi2Sr2Ca2Cu301o+g
Bii 6Pbo4Sr2Ca2Cu30io+8 nanocrystal have been synthesized
using coprecipitation and wet-mixing method. According to XRD
analysis on the 2223 phase formation, it was found that the wetmixing
process exihibited a better method than the
coprecipitation, resulting in samples without and with Pb doping
having volume fraction of 2223 phase exceeding 85,80% and
87,57% respectively, after sintering at 840°C for 8x1hour. The
corresponding samples have Tc = 79,6 K and 98,3 K; and crystal
size of 170,30 nm, 216,47 nm. Sample also demonstrated a
ferromagnetic effort for 2223 phase without Pb while with Pb
doping exihibited paramagnetic.
