Abstract:
A process for preparing a material, comprising the steps of:(a) subjecting a gas mixture to a temperature of at least 1,000 degrees Celsius, while simultaneously increasing the pressure of said gas mixture to a pressure of at least 1,000 Torr, thereby producing a hot gas mixture, wherein said gas mixture is comprised of at least about 85 volume percent of inert gas, and at least about 0.1 volume percent of ionized fullerene material, (b) decreasing the temperature of said hot gas mixture to a temperature of less than 500 degrees Celsius in a period of less than about 1 millisecond, and (c) decreasing the pressure of said hot gas mixture from said pressure of at least about 1,000 Torr to a pressure of less than about 1 Torr in a period of less than about 10 milliseconds.
