How fullerite becomes harder than diamond

The scientists suggested that under pressure, part of the fullerite turned into diamond, while the other part remained as fullerite, but in a compressed state within the diamond. After comparing the X-ray spectra, it was assumed that most likely in the experiment, they had obtained an amorphous carbon medium with a hydrostatically compressed fullerite inside, while the model dealt with a diamond containing a fullerite inside. According to the calculated spectrum, the new model correlated very well with the experimental data. …read more
