In general, the purity and grade of lump/vein graphite is relatively much better in comparison with the flake counterpart. However, flake graphite is much more appropriate for many practical applications [35]. Crystalline flake graphite, Plumbago, is a plate-like particle with a hexagonal structure with irregular fragmented edge [36], [37 ...
