| Abstract: | C60/C70 synthesis technique by using DC arc is presented in this paper. The production rates of soot and the extraction rates of C60/C70 from soot as a function of atmospheric pressure and arc current in helium and argon have been measured. Under the conditions of 150 mmHg pressure of helium and 65 A arc current, the production rate of soot was 34% and the extraction rate of C60/C70 was 17%. |
