Control of Surface Morphologies and Crystal Structures of Potassium Titanate Fibers by Flux Method
In this work, flux method is used to control the surface morphologies and crystal structures of the fine K2Ti6O13 fibers. When K2CO3 as a flux is added into fine K2Ti6O13 fibers and heated at 1100oC for 2h, the crystal of fibers are transformed to K2Ti4O9 and K2Ti2O5, however, the resulting fibers have no significant change in morphologies. On the other hand, when KCl is used as flux (15wt%) and heated at 1200oC for 2h, the diameters of the resulting fibers become about 2 micron without any change of the crystal structure.
