碳纳米管产品的制备采用了电弧法。详细论述了该系统的设计和电气方案，以及各方面的技术特点。在热分析(TGA和DTA)的基础上，结合透射电子显微镜和富勒烯溶解试验，对所有工艺方案的结果进行了讨论。结果表明，碳纳米管主要形成致密的阴极沉积(“短桩”)。实验确定了短桩择优生长的条件。这些条件的参数范围很窄，这可能会给CNT生产的规模化带来一些困难。
Electric-arc discharge deposition (EADD) is used to produce CNT products. The design and electric scheme are discussed in details, as well as all technological features. The results of the outputs of all technological schemes are discussed on the basis of thermal analysis (TGA and DTA), supported by TEM and fullerene-dissolving tests. It is established that CNTs mainly form as compact cathode deposits ("stubs"). Conditions of stub preferential growth are experimentally defined. These conditions have narrow range of parameters that may cause some difficulties in scaling of CNT production.
