High quality and low cost manufacture of potassium titanate whiskers

Potassium titanate whisker (PTW) is an advance material. The method of the large scale manufacturing PTW is a bottleneck in the application of this material. Hydration of the sinter is the key step of the PTW synthesis. In the present work, ionic exchange equilibrium and mass balance in the hydration are integrated to establish a predictive model describing the conditions of the hydration process. The results show that the aimed product can be controlled mainly by pH during hydration. The amount of water (V₀) is reduced to 1/10 comparing with the literature. The pH and water volume are both controlled easily in a large scale production.
