摘要： 二氧化钛在自然界中存在三种结晶形态:金红石型、锐钛矿型和板钛矿型.金红石型TiO2因其折射率高,性能优越,因而得到广泛的应用[1～3].传统金红石型TiO2的制备需经高温固相反应,经历由无定形→锐钛矿→金红石的转化过程.

关键词: 金红石型, 二氧化钛, 胶溶

Abstract: Rutile titania crystals were directly prepared in liquid system without anatase-to-rutile transformation, while Ti(SO4)2and ammonia are the raw materials. The process of preparation can be divided into two parts: one is precipitating, the other is peptizing. The conditions of precipitating influence the structure of the resulted crystals, even though Ti(OH)4precipitates obtained during precipitating are amorphous. Peptizing is the process of the formation of crystals, the amorphous Ti(OH)4precipitates changing into titania with the change of rutile structure.

Key words: Rutile, Titania, Peptizing
