Study on microstructure and crystal growing of the potassium hexatitanate whiskers reaction synthesized

The morphologies,microstructure and growth of the potassium hexatitanate whiskers was analyzed by XRD,SEM,TEM.The results showed that K2Ti6O13 whiskers reaction synthezed have higher superficial quality,being stylolitic in shape.Array of its interior atoms was very inerratic and crystal dislocation was not found.Side surface and terminal surface of whiskers have a transition layer of atoms staggered arrangement.The growth direction of whiskers is along their axial and radial.And the axial coarsening rate of whiskers is faster.The axial growth direction parallels to [010] orientation.
