Abstract

We attempted to grow single crystals of Bi2Sr2CaCu2Ox (Bi-2212) by Traveling Solvent Zone Melting (TSZM) technique using a gold crucible to stabilize the molten zone as well as to control the composition of Bi-2212 single crystals. As the results of crystal growth, chemical composition of the grown crystals was determined to be Bi: Sr: Ca: Cu = 1.97(4): 1.75(7): 0.88(3): 2.0, which was close to that of feeds. TSZM growth may be effective on the control of composition of Bi-2212 crystals. Superconducting properties of the grown crystal of Bi-2212 were TcTconset=85 K andΔTc=10 K.
