Potassium hexatitanate whisker was effectively prepared with calcination and flux method by using industrial $TiO_2$, $K_2CO_3$ and $K_2MoO_4$ as the starting materials. When it was synthesized by the calcination method, the filtrate after boiling water treatment was required a neutralization, as the pH of filtrate was higher than 9. Because K component was very small, recovery of K component was not economically suitable. In case of flux method, flux was recovered 96.1% of Mo component and 91.8% of K component at $K_2MoO_4$, for 10th treatment in boiling water of 100ml to 10g.
