Abstract: BiVxSrCaCu2 Oysystem glasses were prepared by using doubleroller quenching method. Thedifferentialthermal analysis was employed to investigate the effect of V doping on glass forming ability( GFA). Theresultsshowedthatthe GFAof Bisystem increases withthein creasing ofthe amountof Vdoping. Thebestatomic ratiofor having both superconductivityandthegreatest GFAwas BiV0 18 CaCu2 Oy .

Key words: analysis Bisystem glass, Bi based high TCsuperconductors, differentialthermal
