中文摘要 | 在馬達帶動式的細長型電弧放電反應爐中,碳60粉末產率被觀察到與氦 氣流量有密切關連,本文就其中反應的可能模式加以探討。同時,以溶液相長晶 法可成長大小約1mm�蘆犖�60晶體;並利用EI質譜儀和X-ray繞射分析碳60結晶粉 末的特性;及熱差/熱重分析儀探討碳60結晶粉末在空氣,氮氣,及氦氣下的熱反 應作用。 |
英文摘要 | In an automatic-driven arc furnace reaction chamber with large aspect ratio (= length/innerdiameter), the production yield of C�� Powder was observed to be very close related to the helium gas flowrate. A model is proposed to explain this relation. In the meantime, solution growth technique is applied to obtain C�� crystals of about 1 mm�� size. The properties of the as-obtained C�耶�� powder and crystals are determined by Electron-Impact (EI) mass spectrum and X-ray diffraction (XRD). The thermal reaction of C�� in the flow of air, nitrogen gas, and/or helium gas studied by the DTA/TGA analyses are alsorenorted. |
