Experimental study of physical parameters significant in fullerene synthesis
Апстракт
In this work, the effect of physical parameters on the yield of fullerene, synthesized in a hollow cathode plasma reactor is investigated. The experimental investigations done previously have shown that the fullerene yield depended on tehcnical parameters - the current intensity, inert gas pressure, type of gas and interelectrode gap. The aim of this work was to show that the fullerene yield depends on physical parameters - carbon concentration, carbon flow rate from the interelectrode gap, axial temperature and temperature gradient between the. arc channel and the chamber walls as,well. It was found that fullerene synthesis occurs in an inert heat bath with dimensions determined by die temperature gradient. The lower temperature limit is around 2000 K and the value of the upper limit is die value of the axis temperature which depends on the discharge conditions. The synthesis of fullerenes is more effective if the carbon concentration in the heat bath is large and the carbon flow rate... from that zone to colder parts of chamber is small.
