摘要：

We have used differential scanning calorimetry, optical microscopy, and x-ray diffraction to study the thermal stability of pristine C-60 in the solid state. To minimize contamination and/or reaction of the sample with the container, sublimed single crystals and powder derived from resublimed C-60 material were heated in hermetically sealed Au pans. Crystals heated at 1260 K for more than 10 min decomposed into amorphous carbon without losing their faceted morphology.
