Abstract

Abstract This paper reports that Zn 3N 2 powder of high quality has been synthesized by a nitridation reaction of Zn powder with NH 3 gas (flow rate 500 ml/min) at the nitridation temperature of 600 °C for 120 min. X-ray diffraction indicates that Zn 3N 2 is cubic in structure with the lattice constant being a=9.788 Å. X-ray photoelectron spectroscopy shows the differences of chemical bonding states between Zn 3N 2 and ZnO, and confirms the formation of N–Zn bonds. Thermal gravimetric analysis and differential thermal analysis are employed to investigate the thermal decomposition behavior of Zn 3N 2 powder. It is found that Zn 3N 2 is unstable when exposed to open air above 500 °C.
