A sol-gel technique including the Pechini process has been employed for the preparation of nano-sized zinc titanate (ZnTiO3) powders. The yielding powders were heated at temperature from 500°C to 1000°C for various times. The ZnTiO3 phase was formed at the beginning of 500°C. The shape of crystalline will be changed from granular to fiber as the calcination temperature increasing from 800°C to 1000°C. The activation energy of crystallization of ZnTiO3 is 172.74 kJ/mol calculated from Kissinger's equation. The activation energy of grain growth is 20.83 kJ/mol experimented by Arrhenius equation.
