The prepared nanotubes and nano-th ickness sheets of titanate were amorphous,wh ich beared the sim ilar behaviors of phase transform ation during the process of calc inations.Both of them began to transform into anatase TiO2when the temperature was over 300℃,and rutile TiO2in long rod shape were form ed in the temperature about 700℃.It was believed that the sim ilar inner structure led to the sim ilar behaviors of phase transfrm ation.
