Abstract

Plasma-detonation synthesis was developed to synthesize the superhard material C₃N₄. The method integrates the advantages of plasma and detonation in carbon nitride preparation. In the method high-tempreture plasma was supplied through high-voltage impulsing power source, TNT was detonator and C₃N₆H₆ was reactant. The samples of prepared were analyzed and characterized by the ways of SEM, EDS, XRD and FTIR. The results show that average crystalline size is 1.1μm, and most particle is hexagon. The quality ratio of carbon to nitrogen is about 1.00 : 1.77 and the products are mainly α-C₃N₄ and β-C₃N₄, g-C₃N₄ and a few of CNx phase. The main valence bonds are C-N and C=N.
