Abstract The last key step in the preparation of titanium dioxide was dehydration of metatitanic acid. The kinetics and mechanism of metatitanic acid dehydration under different heating rates were studied by means of synchronous thermogravimetry. The results show that the oxygen atmosphere would affected the dehydration process. Metatitanic acid was dehydrated quickly in oxygen atmosphere, then slowly until the reaction completed, while carried out at a slow rate in anaerobic atmosphere (argon and nitrogen). Using the method of non-mode function and mode function to calculate the kinetics of dehydration of metatitanic acid. The dehydration reaction in the air atmosphere meeted the Avrami-Erofeev equation which controlled by the formation and growth of the crystal nucleus. When the dehydration reaction in the anaerobic atmosphere, according to the Mampel Power law, it was consistent with the one-dimensional boundary reaction.The results will provide an important reference for further understanding the calcination and decomposition of titanate, and the dehydration process of related hydrous titanium oxides.

Key words： metatitanic acid dehydration different atmosphere kinetics
