| 摘要: |
| 本文以钛酸丁酯为原料, 通过溶胶一凝胶法制备了TiO2凝胶, 在高温下烧结此凝胶得到TiO2。将TiO2 粉末在900℃以上用氨进行氮化, 制得金黄色的氮化钛。通过使用热分析、色谱分析、扫描电镜及X一射线衍射等手段, 研究并揭示了凝胶在陶瓷化生成TiO2 的过程中的化学反应, 结晶及晶型随温度的变化规律。发现了氮化钛陶瓷的生成率与TiO2 溶胶的制备条件之间的关系。 |

| Abstract: |
| Titanium oxide gel was preared from n-butyl titanate by a sol-gel method, The gel was then sintered to form TiO2 ceramic. From the TiO2 powder, titanium nitride formed through nitrifying by ammonia at the temperature above 900℃. The processes were intensely studied through thermal analysis, chromotography, scanning electronic microscopy and X-ray diffraction. Emphasis is placed on the chemical reations, the crystalliztion and polyamorphism in the sol-gel process of TiO2. Thereafter, the dependence of the yield of TiN under the preparatory conditions of TiO2 is established. |
