Abstract

The availability of bulk single crystals is indispensable for the systematic study of the intrinsic properties of superconducting oxides. Hence, there is a need to find an optimum method of growing these materials. In this manner, the flux method has proved to be an effective technique of growing large BSCCO (2212) single crystals due to the relative ease with which these single crystals are produced.
In our previous study, we were able to grow large superconducting (needle-like and plate-like) Bi-2212 single crystals using the KCl/KCl-Bi2O3 flux methods. However, the crystals produced were thin and had rough, uneven surface due to the presence of the residual flux that adhered on the crystals. In this study, we were able to improve the quality of the crystals by removing this residual flux with ether and nitric acid. Also, the preferential growth of the crystals was determined and platelets of good quality were obtained by modifying the temperature program.
