| 摘 要： | 用廉价的 Ti Cl4 作原料 ,采用简单易行的沉淀法制备出了平均粒径为 2 0 nm的锐钛矿型纳米 Ti O2 粉体 ,确定了最佳煅烧温度为 5 0 0℃。 XRD结果表明 ,40 0℃煅烧后的产物为锐钛矿型纳米 Ti O2 ,在 60 0℃煅烧后的产物仍保持锐钛矿晶型 ,而在 70 0℃煅烧后的产物才开始出现金红石型 Ti O2 ,但粉体的主要晶型仍为锐钛矿型

| Abstract: | Anatase powder whose average size is about 20 nm is prepared by precipitation reaction of TiCl 4 to NH 3·H 2O at room temperature. Thermal analysis and XRD experiments show that the optimal calcination temperature is 500 ℃. The XRD experiments indicate that the powder calcined at 400 ℃ crystallizes in crystalline structure of anatase. The powder is still anatase after being calcined at 600 ℃. No rutile diffration peak appears in spectra before the powder is calcined at 700 ℃. |
