摘要
Ti、Al和C组成的Ti:Al:C=2:2:1(摩尔比)系的燃烧合成产物主要物相为Ti_3AlC_2,在体系中添加Ti_3AlC_2形核后,Ti_3AlC_2的生成量增多,有利Ti_3AlC_2的燃烧合成;添加固体NH_1Cl,燃烧合成产物主要物相为TiC,不利于燃烧合成Ti_3AlC_2,并从热力学的角度作了解释.
Combustion product with the main phase Ti_3AlC_2 is synthesized through combustion synthesis
process by using Ti, Al and C powders as raw materials. The Experimental results show that the amount of the final
product Ti_3AlC_2 is increased by addition of Ti_3AlC_2 as seed crystal. However, TiC becomes the main phase with
the addition of NH_4Cl in the raw materials. The above experimental phenomena are explained with thermodynamice
analysis.
