| 摘 要： | 采用部分中和法制备超细TiO2粉体,通过TEM、XRD和TG-DTA对产品进行了表征,指出水合TiO2在煅烧过程中逐步失去游离水和化合水,再形成TiO2结晶,且随着煅烧温度的上升,颗粒的粒度迅速增大.在600℃以下煅烧时所形成的TiO2颗粒为锐钛型,在800*!℃时完全转化为金红石型.

| Abstract: | Ultrafine titania was prepared by a partial neutralization process and characterized by TEM, XRD and TG DTA. It is shown that TiO2 crystal is formed through the evaporation of free and chemically combined water from hydrated titania in the process of calcination and TiO2 particle size increases rapidly with the increase in calcination temperature. Anatase was formed when the calcination temperature below 600℃ whereas it transformed into rutile when the calcination temperature reached 800℃. |
