Abstract

Abstract

High purity titanium dioxide was prepared through the hydrothermal synthesis route, using metatitanic acid as precursor which was hydrolyzed from low concentration industrial titanyl sulfate solution via short sulfate process. The effects of slurry mass concentration, hydrothermal temperature and hydrothermal time on the structure and purity of the products were investigated. The samples were characterized by XRD, particle size distribution, BET analysis, SEM and TiO₂ content determination. The hydrothermal conditions, e.g. slurry mass concentration, hydrothermal temperature and hydrothermal time influence the dissolution, nucleation, crystal growth, polymerization and agglomeration of the precipitates, and the structure, particle size distribution and specific surface area of the hydrothermal metatitanic acid are also affected, which leads to the content variation of the adsorbed impurities and ultimately influences the structure and purity of TiO₂. The optimized hydrothermal conditions are the slurry concentration of 160 g/L, hydrothermal temperature of 140 ℃ for 36 h, with the high purity TiO₂ (99.99%) obtained.
