Abstract
A comparative efficiency analysis of fullerene synthesis methods showed the advantage of the arc method and the output limit of arc discharge devices with various geometries: α = 19 ± 4% and 33%. In order to increase the output, working gas flow is introduced in the hollow electrode with arc discharge using a ceramic insulator (alundum crucible). Under such conditions, the formation time of fullerenes in the high-temperature space is longer and the cluster concentration is higher; therefore, the output of heavy fullerenes and product without amorphous component increases. It is planned to use, instead of alundum an insulator made of boron carbonitride.
