| 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. |
