Effective Synthesis of Silicon Carbide Nanotubes by Microwave Heating of Blended Silicon Dioxide and Multi-Walled Carbon Nanotube

Abstract: Silicon carbide nanotube (SiCNTs) has been proven as a suitable material for wide applications in high power, elevated temperature and harsh environment. For the first time, we reported in this article an effective synthesis of SiCNTs by microwave heating of SiO 2 and MWCNTs in molar ratio of 1:1, 1:3, 1:5 and 1:7. Blend of SiO 2 and MWCNTs in the molar ratio of 1:3 was proven to be the most suitable for the high yield synthesis of β-SiCNTs as confirmed by X-ray diffraction pattern. Only SiCNTs were observed f… Show more

“…After that, many modifications have been made by several researchers for industrialization of this process. Recently, microwave heating and different catalyst activities have been investigated for the preparation of SiC from RH through different studies [202][203][204][205]. Certain metallic catalysts (Co, Fe, Pd, Ni, and Cr) are significantly enhanced the reaction kinetic between SiO 2 and C in the temperature at 1200-1600°C.…”

“…Как правило, квазиодномерные SiC-наноструктуры, включая нанотрубки, синтезируют " снизу-вверх" в рамках механизма паржидкость-кристалл (ПЖК) с использованием различных катализаторов роста [7][8][9][10]. Также их формирование может осуществляться путем самокаталитического роста, с помощью масок [11] или по механизму пар-кристаллкристалл (ПКК) [12]. При этом во всех случаях рост SiС-наноструктур происходит от подложки вверх, т. е. "…”
