-Cl whisker with well-defined shape
distinct intercalated structure
regular quality
and welldispersing capability could be obtained under the following conditions: buffer solution volume ratio of 40%
reaction temperature of 80 ℃
and reaction time of 148 h. The whisker obtained was well-crystallized and had the morphology of homogeneous and fiber bar.
