摘要：

We report the growth of pure, high-quality Bi2Sr2CaCu2Ox (BSCCO 2212) crystals, grown by a novel flux method in Pt crucibles. The growth process involves repeated remelting and recrystallisation of the same melt. The crystals appear to be chemically pure, contain no Pt contamination and demonstrate a very high as-grown T(c) (onset), above 92 K, and the majority in the range 93-95 K with transition widths (10-90% level) between 4 and 8 K. The lattice parameters of a typical crystal are a=5.414(2) angstrom, b= 5.413 (2) angstrom, c= 30.893(12) angstrom. We discuss the growth process and the qualities of these crystals.
