Recent functional research using pressurization on polyhedral graphite particles "G balls", which are one of carbon nano-structured materials, are reviewed in this article. The high-pressure structural-study shows the polyhedra maintain the graphite phase under pressure higher than 40 GPa. We could understand the closed and solid framework of G balls contributes to stability and high volume elasticity of the graphite phase. Therefore, it is reasonable to suppose that G balls have a hydrogen-barrier effect in addition to a ball-bearing function when they are applied to a solid lubricant inducing rolling friction.
