What is the difference between carbonaceous slate and graphite?
Carbon is a non-metallic element, located in the second periodic IVA family of the periodic table
[1] Since each carbon atom emits an electron, those electrons are free to move, so the graphite belongs to the conductor. Graphite is one of the softest minerals, and its use includes the manufacture of pencils and lubricants
Graphite is an elemental element of elemental carbon. Each carbon atom is surrounded by three other carbon atoms (arranged in a honeycomb-like hexagon) to covalently bond to form a covalent molecule.
Carbon slate is a plate-like structure, basically no recrystallization of the rock, is a metamorphic rock, the original rock is muddy, silty or neutral tuff, along the plate direction can be stripped into thin slices. The color of the slate varies with the impurities it contains.
