The formation of the high Tc phase of melt quenched Bi1.6Pb0.4Sr2Ca2Cu3Oy
The melt quench method was applied in the fabrication of Bi1.6Pb0.4Sr2Ca2Cu3Oy superconducting ceramics. The effects of melting the lead doped BSCCO were investigated using the scanning electron microscope and energy dispersive spectroscope (SEM/EDAX), differential thermal analyzer (DTA), x-ray diff...
