Effect of Energy on Plasmodynamic Synthesis Product in the Carbon-Nitrogen System

Abstract

Carbon nitride (CNx) powders were synthesized in the high-speed carbon electric discharge plasma jet flowing into the chamber filled with the nitrogen atmosphere at normal conditions. A coaxial magnetoplasma accelerator (CMPA) was used to generate the plasma flow. The CMPA was supplied from the pulse capacitive energy storage. Effect of input to the CMPA energy value on powders was studied by using several analytical methods (XRD, TEM, XPS). According to XRD with the increasing of input energy value the content of CNx in the product increased about 1.5 times. Its in a good accordance with the XPS data according to which the presence of nitrogen increased from 0.5 to 1.4 mass percent. Furthermore, the particles morphology was noticeable changed with the energy increasing. The obtained results revealed that by changing the energy parameters of the capacity energy storage its possible to influence on the product synthesized in the carbon-nitrogen system.
