초록
Potassium tetratitanate (K2Ti4O9) whiskers with an average diameter and aspect ratio of 1-3 μm and 20-30 respectively were synthesized by calcinating mixtures of industrial grade potassium carbonate (K2CO3), anatase TiO2 and potassium fluoride (KF). The effects of the titanium compounds, molar ratio of K2O/TiO2 and content of KF on the morphology of the whiskers were investigated. The results indicated that the addition of KF improved the growth of potassium tetratinate crystals.

The results indicated that the addition of KF improved the growth of potassium tetratinate crystals.
