Description

A method for the preparation of high Tc superconductor (HTSC) Bi2CaSr2Cu2O8+δ involving three steps has been adopted. Firstly two compositions namely Bi2O3 + CaO and SrCO3 + CuO were prepared, these were then mixed in the molar ratio 1:2. Short duration heat treatment at temperature approaching melting stage, which here was well above 9000C due to pre-conversion of Bi2O3 into CaBi2O4, resulted in formation of material rich in the desired phase. Characterisation of samples by XRD, EMPA, electrical and magnetic methods is done
