摘要: 以纳米TiO2为原料,采用氨气氮化法制备了纳米TiN粉体。研究了制备过程中的影响因素。实验结果表明:在800℃下,氮化反应5h,纳米TiO2全部转化成纳米TiN,制备的纳米TiN粉体的粒径为20nm左右,采用化学分析法分析了纳米TiN的纯度,采用DTA-TG技术研究了纳米TiN的热稳定性。

Abstract: Nano TiN powders were prepared by the ammonium nitridation method using nano Ti02 powders as starting material. The effect of nitridation reaction conditions on the properties of nano TiN powders was studied. The purity of nano TiN powders was analyzed by the chemical method. The thermal stability of nano TiN powders was studied by the DTA-TG technique. The experimental results show that nitricled at 800℃for 5h, nano TiO2 powders are completely converted into nano TiN powders. TEM micrographs show that the size of nano TiN particles is about 20nm.

Key words: nano TiN, nano TiO2, preparation, influence factors
