Abstract
Aluminum nitride was synthesized using a carbothermal method from mesoporous alumina having a high surface area (< 1,000 m2 /g) as an aluminum source and CNTs (carbon nano tubes) as a carbon source. In this case the mesoporous alumina was used as the starting material instead of ��-Al2O3 with the expectation that the mesopores in mesoporous alumina act as channels for N2 gas and elimination of CO generated as by-product. It is also expected that the synthetic temperature should be lower compared to the use of ��-Al2O3 as a starting material due to its high surface area. The crystallinity of the produced aluminum nitride was studied by XRD and FTIR, and the microstructure was investigated by FE-SEM. Also the purity of the aluminum nitride was analyzed through N/O determinator and ICP analysis.
