Abstract

Potassium hexatitanate (K₂Ti₆O₁₃) powders were synthesized by sol-gel method using supercritical drying to produce ion-exchangeable fine powders with high surface area. The effects of titanium alkoxides and mole ratios of K/Ti were investigated. By using sol-gel method, potassium hexatitanate powders were obtained at 630°C which is 350°C lower than that by melting method. The surface area of this sample was about 30-40 m²/g which was higher than that of melting method sample. Addition of H₂O and decrease in mole ratios of K/Ti increased surface area of powders.
