不溶于醇，而溶于稀酸中，冷水中溶解较慢，在热水中易分解。 用作媒染剂、催化剂、还原剂、染料褪色剂等，还用于电镀。 硫酸氧钛（IV）-水合硫酸盐用于制备具有锐钛矿型结晶壁的中孔二氧化钛颗粒。它也被用作水溶性前驱体，用于通过喷雾干燥制备掺Nb的TiO2纳米粒子。它可用于钛介观结构的合成。 Titanium(IV) oxysulfate - sulfuric acid hydrate was used in the preparation of mesoporous titania particles having anatase-type crystalline wall. It was also used as water-soluble precursor for the preparation of Nb-doped TiO2 nanoparticles by spray drying. It may be used in the synthesis of titanium mesostructure.
