Low-temperature thermal reduction synthesis of nano-structured TiC via TiO2-template growth method
Source abstract
Abstract
Titanium carbide has attracted much attention as a transition metal carbide. This study proposed a novel method for the preparation of different-morphology nano TiC materials by direct carbothermal reduction of TiO 2. TiO 2 raw materials with different morphologies were used as template and titanium source, and highly reactive CaC 2 was served as reducing and carbonizing agents. TiC nano materials with the morphologies of particle, rod and line were successfully prepared at a low temperature of 1000 ℃ for 2 h under vacuum condition, which well inherited the morphologies of TiO 2. Moreover, the prepared different-morphology TiC materials showed total electromagnetic shielding effectiveness of higher than 60 dB, demonstrating the potential application of the different-morphology TiC in the field of electromagnetic interference shielding. This study proposes a new method for the TiC preparation under conditions of significantly lowered reduction temperature and time, and provides a new nano TiC formation path which is controlled by the "titanium template generation" mechanism.
