Nano-Synthesis of Promising Families of HTc-Superconductors to Save Electrical Loss in the Electrical Saudi Arabia Net ( Freeze Dry Synthesis of Nano-Zr-Added-2212-BPSCCO-Superconductor )

摘要

Saving energy loss through the conduction is the major goal for many advanced countries so superconductors are the essential material to achieve such these dreams . The present investigations were concerned by synthesis of pure BPSCCO (Bi 0.5 Pb 0.5 ) 2 Sr 2 Ca 1 Cu 2 O 8 and its variant zirconium containing composites with general formula : Bi 1+x Zr x PbSr 2 Ca 1 Cu 2 O z and , where x = 0.1 ,0.2 and 0.3 mole % respectively ,were prepared via soultion route (Freeze Drying Technique ) to obtain nano-product . ZrO 2 has a limited effect on the main crystalline superconductive 2212-phase as x amount added increase as indicated in XRD measurements .SE-microscopy accompanied with EDX proved that, solution route was the best in the degree of homogneties and exact molar ratios . ZrO 2 exhibits strong interactions on Raman spectral modes of 2212-phase . ZrO 2 has a slight effect on Tc’s even with maximum addition x = 0.3 mole . Finally the application of ZrO 2 -nano-additives to the 2212-BPSCCO superconductors enhance the super-conduction mechanism and consequently save too much the amount of electricity loss on the main nets of electricity.
