摘要

The reaction and crystallization mechanism of K₂Ti ₂O₅ fibers from amorphous titania and K₂CO ₃ by a calcination method at low temperatures are investigated in this study. K₂Ti₂O₅ nuclei are formed in the solid-state reaction stage at 640°C due to the suppression of TiO ₂ crystal growth in the presence of K₂CO₃. K₂Ti₂O₅ nanofibers are obtained in the crystallization stage at 820°C due to the appearance of K₂O melts. The separation between the nucleation and the fiber growth process is critical to control the morphologies and microstructures of K₂Ti ₂O₅ fibers at low temperatures.
