【Abstract】 With TiO₂ and K₂CO₃ the main raw materials, and potassium titanate whiskers were prepared by Liquidus-assisted method according to different cooling programs, adding different fluxes and different raw material ratios. The morphology was characterized by SEM. The results show that the potassium titanate whiskers prepared by cooling in three stages, adding KCl flux, the molar ratio of K₂CO₃ and TiO₂ of 1.1∶6 have complete morphology, smooth surface, good dispersion, length-to-diameter ratio of（35-45） ∶1. This process optimizes the nucleation and growth of whiskers through precise control of thermodynamic conditions, providing key process parameters for the industrial production of potassium hexatitanate whiskers, which lays a foundation for their applications in high-temperature materials, composite materials, and other fields.更多还原
