摘要
Abstract
In the production process of titanium dioxide by sulfuric acid method,the selection of salt treatment agents has a significant impact on the surface properties of rutile titanium dioxide crystals.Thus it is necessary to carry out an in-depth study to reveal the differences in the surface properties of titanium dioxide caused by different salt treating agents.In this study,the differences in surface mor-phology,crystal surface defects,and surface hydroxyl groups of rutile samples treated with zinc-based salt and aluminium-based salt were investigated using SEM,XPS,and BET instruments,respectively.The results show that the aluminium salt-treated rutile samples present elongated shape and suffer from greater sedimentation resistance during the sedimentation process.Meanwhile,the aluminium salt-treated rutile samples have more crystal defects and surface hydroxyls on the surface than the zinc salt-treated samples,and also have more pronounced dissociative effects on water molecules,higher surface potential in the water-dispersed system,and are more capable of forming more stable dispersed systems.关键词
