项目摘要

1) A JxB arc jet fullerene continuous producer with chip-type carbon material introducing system is developed. In a Crucible type anode, chip type carbon is filled up and is supplied by dropping from carbon material stock when it is consumed. By a comparation method, the arc condition is automatically controlled (maximum discharge current is 300 A). By applying steady-state magnetic field, arc plasma including carbon vapor is jetted out by JxB arc jet force, which increase fullerene production rate seriously (about 7 times).2) By using this machine, carbon soot is produced at 10 g/h for the discharge current of 200 A.C_<60> content is about 10-20 W%. C_<70> content is about 2-4 W%. Higher fullerene (C_<76>, C_<78>, C_<82>, C_<84>) contents is about 0.2 W%.3) Lanthanum endohedral metallofullerenes are produced by this machine with carbon-La_2O_3 composite chip and mixture of carbon chip and La_2O_3 powder. Production of LaC_X (x=60,62,64, ...) is confirmed by the laser desorption time-of-flight mass spectrometer. By the Soxhelet method, LaC_X (x=72,74,76, ...) are extracted. LaC_<60> and LaC_<70> are also extracted by low-temperature ultrasonic extraction method, which are not stable in hot organic solvent. La@C_<82> content in the soot is bout 0.2 W%.4) From this study, revolver type fullerene automatic producer is developed. It is manufactured and started to cell by Daia Vacuum company in Japan.

1）开发了带有芯片型碳材料引入系统的JXB ARC Jet Fullerene连续生产商。在坩埚型阳极中，芯片类型的碳被填充，并在消耗碳材料时从碳材料中滴下来提供。通过比较方法，弧条件自动控制（最大放电电流为300 a）。通过应用稳态磁场，包括碳蒸气在内的ARC血浆由JXB ARC JET力喷射出来，该力量会认真地提高富勒烯的生产率（约7倍）。 C_ <70>内容约为2-4 w％。较高的富勒烯（C_ <76>，C_ <78>，C_ <82>，C_ <84>）含量约为0.2 w％.3）Lanthanum Endohum enehohum enohohefral slallafullerenes由这台机器用碳_2O_2O_2O_3复合芯片和LA_2O_2O_2O_2O_3粉末的碳和混合物生产。 LAC_X的产生（X = 60,62,64，...）通过激光取消吸收时间质谱仪确认。通过Soxhelet方法，提取LAC_X（X = 72,74,76，...）。 LAC_ <60>和LAC_ <70>也通过低温超声提取方法提取，这些方法在热有机溶剂中不稳定。 LA@c_ <82>烟灰中的内容是本研究中的0.2 w％.4），开发了左轮手枪型富勒烯自动生产商。它是由日本的Daia真空公司制造的，并开始使用。
