An automatic producer of fullerence by arc discharge in a closed chamber is developed and production process and parameter dependence of production rate of C60 are investigated. As a result, effective production of C60 is obtained when effective sublimation of carbon atoms from carbon meterials is carried out, when helium gas pressure is adequate to carbon stoms colliding each other frequently in high temperature atmosphere and when impurity gas such as oxygen and water gases are scacely included. In order to realize continuous production for long time, dropping material type new fullerence producer is developed and we succeeded in the synthesis of fullerenes from chip type carbon materials. Production rate is improved remarkably by a JxB type new arc discharge method. It is also improved by a pulse modulated discharge. These results will be useful for industrial scale production of many kinds offullerenes.

研制了一种密闭室中电弧放电富勒自动生产装置，并研究了C60的生产工艺和产率的参数依赖性。结果，当碳原子从碳材料中有效升华时，当氦气压足以使碳原子在高温气氛中频繁地相互碰撞时，以及当杂质气体如氧气和水气时，获得C60的有效生产。都被大规模地包括在内。为了实现长时间连续生产，开发了滴料式新型富勒烯生产装置，成功实现了由片状碳材料合成富勒烯。采用JxB型新型电弧放电方法，生产率显着提高。它也通过脉冲调制放电得到改善。这些结果将有助于多种富勒烯的工业规模生产。
