Combustion synthesis of TiN with liquid nitrogen

Abstract: TiN combustion synthesis are investigated through a self-propagating reaction of titanium powder compacts of specific packing density (40% to 60%) theoretical one) in the presence of liquid nitrogen under atmospheric pressure. As a result of the study on the difference between the upward and downward combustion propagation by changing the ignition point, it was confirmed that the combustion propagation upward was more effective for higher conversion than that downward. In the latter case, the conversion ration did not clearly depend on the packing density of Ti compacts and its maximum was less than 50%, while in the former about 70%. It is considered that both the hear and the evolved nitrogen gas also propagate upward in the case of upward reaction propagation, resulting in higher TIN conversion ratio compared to the downward one.
