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.通常情况下,锐钛矿到金红石型T...

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(SO\-4)\-2 and 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)\-4\} precipitates \{obtained\} during precipitating are amorphous. Peptizing is the process of the formation of crystals, the amorphous Ti(OH)\-4 precipitates changing into titania with the change of rutile structure.
Keywords:Rutile  Titania  Peptizing
