摘要

A sol-gel technique including the Pechini process has been employed for the preparation of nano-sized zinc titanate (ZnTiO_3) powders. The yielding powders were heated at temperature from 500 deg C to 1000 deg C for various times. The ZnTiO_3 phase was formed at the beginning of 500 deg C. The shape of crystalline will be changed from granular to fiber as the calcination temperature increasing from 800 deg C to 1000 deg C. The activation energy of crystallization of ZnTiO_3 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.
