“…Аналогично на морфологию частиц карбида титана может влиять распределение температурного поля в рабочем объеме и количество подведенной энергии. В рассматриваемой системе наличие высокого градиента температуры и скорости ее изменения в зоне формирования дугового разряда постоянного тока не вызывает сомнения, при этом температура плазменного столба дугового разряда снижается при удалении от зоны привязки разряда к электродам [22]. Этот факт может определять формирование нескольких морфологических типов частиц карбида титана.…”

The paper discusses the experimental studies connected with development of scientific and technical foundations for the synthesis method of titanium carbide by electric arc discharge plasma under ambient air condition. According to the X-ray diffraction data, the dependences between the product phase composition and the synthesis duration was determined. According to the scanning electron microscopy and energy dispersive analyses data, a morphological types number of titanium carbide particles, which are formed as a result of uneven distribution of energy in the reaction volume, was identified.

“…Too many Na + ions would hinder carbon ions flying from anode towards the center of cathode. Researchers found that perhaps this is another reason that the length of SWCNT is short and only a single SWCNT [61]. The optimized conditions to synthesize large quantities of SWCNT by applying arc discharge in NaCl solution deserve further investigation.…”

“…To date, the synthesis of CNTs as well as the CNM is carried out by different methods: laser action on metal-graphite electrodes; plasmachemical evaporation of graphite in a gas [7][8][9][10][11][12][13][14] and liquid medium in the presence of catalysts [15][16][17][18][19][20][21][22][23][24]; pyrolysis of hydrocarbon structures on catalysts; pyrolysis of benzene in the presence of organometallic compounds (ferrocene and metal phthalocyanides); the dissolution of carbon monoxide on catalysts.…”

This article studies a nanoproduct that is formed by simultaneous plasma-chemical evaporation of graphite and platinum. It was shown that the resulting deposits under different synthesis conditions have a similar and well-defined structure and consist of two main parts (core and enclosing bark). The structure of both parts is investigated at the micro-and nanoscale levels. The products of synthesis and similar products obtained without the use of platinum has been compared. The distribution of platinum in synthesis products is studied. It is proved that the atoms of the platinum catalyst influence the process of formation of the deposit. Namely, it stimulates the formation of a deposit where the deposit core containing platinumcontaining bundles of CNT exists as an independent core that does not have a strong connection with the deposit shell. It is found that differential-thermal analysis of CNM in air by the methods of TG, DTG, DTA allows to reveal insignificant differences in the heat resistance of different carbon nanostructures, and thus it can be used for their identification. Such studies are of great importance for the synthesis of platinumcontaining catalysts for fuel cells and other chemical industries.
