摘要

在同轴磁等离子体加速器(CMPA)产生的超高速放电等离子体射流中,在“碳-氮”体系中合成纳米分散粉末的可能性。等离子体在充满气态氮的加压室中提供。最多1克的黑色粉末产品合成一个工作周期,持续时间约为100毫秒。根据x射线衍射和透射电镜数据,该产物由石墨和接近αC3N4结构的两种主要晶相组成。

Synthesis of crystalline phases in the system «carbon-nitrogen» in a hypervelocity electric discharge plasma jet
The possibility is shown to synthesize a nanodispersed powder in the system “carbon-nitrogen” in a hypervelocity electrical discharge plasma jet generated by a coaxial magnetoplasma accelerator (CMPA). The plasma shot is provided in the pressurized chamber filled with the gaseous nitrogen. Up to 1 gram of black powdered product is synthesized for one working cycle having a duration about 100 ms. According with the X-ray diffraction and transmitting electron microscopy data, the product consists of two main crystalline phases such as graphite and the structure closed to the αC3N4 structure.
