Description
Leibo Ji and co-authors compare graphite made from coal by nature and by furnace, in a 2026 study. Coal can slowly graphitize underground or be forced at high temperature, and how well the product carries electricity decides many uses. Samples across both series were examined with diffraction, Raman spectroscopy, and electron microscopy.
Structure grew more ordered as burial grade or furnace heat rose, though several nanoscale graphite types shared each sample, showing the change is patchy. Raw anthracite barely conducted, while natural graphite from coal conducted better than the furnace-made series, yet both trailed well-crystallized flake graphite. The authors name three controls on conductivity: ordering, nanopore structure, and how the graphitized grains pack.
