Can we make graphite from coal? Researchers start by finding new carbon solid

"carbon has an overwhelming tendency to layer—like graphite, but with many 'defects' such as pentagons and heptagons (five- and seven-member rings of carbon atoms), which fit quite naturally into the network. We present evidence that amorphous graphite exists, and we describe its process of formation. It has been suspected from experiments that graphitization occurs near 3,000 K, but the details of the formation process and nature of disorder in the planes was unknown"
