  A flux-free solution to the growth of large and composition homogeneous
superconducting FeSe crystal is reported for the first time, which is based on
the traveling-solvent floating-zone technique. The size of the crystal samples
prepared by this approach is up to 15x6x2 mm3, being far bigger than previously
reported in all dimensions, and the main phase of the crystals is of a single
preferred orientation along the tetragonal (101) plane. X-ray diffraction
analysis identifies the main phase to be the superconducting tetragonal
\b{eta}-FeSe. The superconducting transition temperature (TC) is determined to
be 9.4 K by AC magnetic susceptibility and electronic transport measurements. A
nearly perfect diamagnetic shielding of -97% is observed, indicating a bulk
superconductivity in the crystal sample.
