Powder compacts of the system Bi2–xPbxSr2Ca2Cu3Oy with 0 ≤ x ≤ 0.5 molar ratio using both techniques;isothermal hot pressing and the solid state reaction (sintering). The XRD of the hot pressed powder compacts of t...
A scanning electron microscopy study of the morphology of laser ablated superconducting targets. bothYBaCuO and BipbSrCaCuO, was reported. The effects of laser ablation on target structures are illustratedto provide a...
The effects of sintering on the microstructure and the critical current density of Ag-sheathed BiPbSrCaCuO (2223) superconducting tapes prepared by the powder-in-tube technique were in- vestigated. The microstructure ...
