Abstract :
HTSC Bi1.8Pb0.3Sr2Ca2Cu3Ox of low density has been synthesized and its structural and physical properties have been studied. Scanning electron microscopy (SEM) image shows that the material obtained has porous “foam” structure. The levitation force measured for the porous Bi1.8Pb0.3Sr2Ca2Cu3Ox is appeared to be approximately the same as for polycrystalline YBCO of high density. These “foam” structures may be an ideal material for some practical applications of HTSCs in bulk form.
