The mole ratio of potassium carbonate to metatitanic acid and the calcination temperature and time were crucial to the formation of different-structured potassium titanate whiskers. Well-crystallized potassium tetratitanate whiskers were prepared at a calcination temperature of 1000 °C when the mole ratio of potassium carbonate to metatitanic acid was 1:2.5. Potassium hexatitanate whiskers were dominantly formed at 1150 °C when the mole ratios of potassium carbonate to metatitanic acid were in a range of 1:3.5−1:4.5. Well-crystallized potassium octatitanate whiskers were prepared when potassium tetratitanate whiskers were boiled in water and then dried at a high temperature of 400 °C. The growth directions of all the potassium titanate whiskers are along their [010] crystal directions.
