Synthesizing Nano-Scale Titanium Nitride Powders by Solvothermal and Carbothermal Methods


Article Preview

Xerogel was prepared by the sol-gel method using butyl titanate, alcohol, carbamide and glucose as raw materials. The precursor powders were obtained after xerogel was solvothermally treated at 220oC for 2 h. The IR analysis suggests that the precursor with 10% excess glucose gave an absorption peak at 1084.37cm-1, which was assigned to Ti-OH bond, while no such a peak can be observed for that with 30% excess glucose. The prepared precursor powders were then sintered at 1400oC in nitrogen atmosphere. XRD and SEM results indicated that the sintering time and the contents of glucose had great effects on synthesizing titanium nitride powders. The titanium nitride powders with a high purity and a mean grain size of about 35 nm could be prepared by heating the precursor with 10% excess glucose at 1400oC for 6.5 h.
