Natural Graphite Products
Amorphous Graphite tends to be much less reflective in both coarse and fine grained sizes and has a darker colour, bordering on black whilst higher purity flake has a colour closer to silver grey. It has a typically lower value than flake but still has valuable lubrication properties, is conductive and is a very stable product used in coatings ...
Expanded graphite is made by immersing natural flake graphite in a bath of chromic acid, then concentrated sulfuric acid, which forces the crystal lattice planes apart, thus expanding the graphite. The expanded graphite can be used to make graphite foil or used directly as "hot top" compound to insulate molten metal in a ladle or red-hot steel ...
