Abstract

Abstract

The effect of structural evolution of metatitanic acid on sulfur content was investigated by hydrolyzing the industrial TiOSO₄ solution via thermal hydrolysis method with extra-adding seed. The hydrolysis process was divided into fast hydrolysis stage and slow maturation stage, the change of hydrolysis degree conformed to Boltzmann model. The structure of metatitanic acid changed obviously as the hydrolysis proceeded, its structure became more compact due to the aggregation and adjustment of the precipitated particles, with weaker colloidal property and higher TiO₂ content. The microporous and mesoporous structures of metatitanic acid were formed by the aggregation and accumulation of its primary aggregates, and the pores were filled with sulfate and water. Sulfate radical existed in metatitanic acid was mainly in the form of dissolution in adsorbed water, adsorption, bonding, etc. The sulfur content decreased gradually with the increase of TiO₂ content, showing a linear relationship.
