  Single crystal growth of {\alpha}-Na$_x$MnO$_2$ (x = 0.90) is reported via
the floating zone technique. The conditions required for stable growth and
intergrowth-free crystals are described along with the results of trials under
alternate growth atmospheres. Chemical and structural characterizations of the
resulting {\alpha}-Na$_{0.90}$MnO$_2$ crystals are performed using ICP-AES,
NMR, XANES, XPS, and neutron diffraction measurements. As a layered transition
metal oxide with large ionic mobility and strong correlation effects,
{\alpha}-Na$_x$MnO$_2$ is of interest to many communities, and the implications
of large volume, high purity, single crystal growth are discussed.
