Prospects for Natural Graphite Flake Markets

Flake graphite prices are dictated by three factors: Carbon purity: Flake graphite concentrate with a greater carbon purity receive a premium price because they require less processing to remove disruptive impurities. A carbon content of 90% C and above is generally required in all refractory, foundry and crucible applications.
