Diamond is a mineral made up of Carbon.
A mineral cannot be organic. A mineral cannot be made by or composed of life forms.
A milky white mineral made up of silica is quartz. Quartz is the second most abundant mineral on the Earth's crust.
By definition, a mineral must form by natural processes. So anything man-made, even if it is chemically an structurally identical to a mineral, is not a mineral. However, natural diamond is formed from graphite as well.
Marble is primarily composed of the mineral calcite.
Graphene is a sheet of Carbon atoms, or one layer of Graphite ("lead" in a pencil). A graphene filter is a filter made of graphene.
Until recently, diamond would have been the answer, but graphene films have even higher conductivity. But graphene would not (yet) be considered a native mineral. [Most probably]
Graphene is pretty amazing. An adequate description of the properties is rather long. There is a link below to the properties section of an article on graphene.
Graphene is an atomic-scale honeycomb lattice made of carbon atoms. It is the world's first 2D material and is one million times smaller than the diameter of a single human hair
Graphene is formed by peeling extremely thin layers of graphite off of a larger piece, in the original paper published on graphene it was done using tape.
Graphene is a very thin layer of graphite. It is so thin, it is so close to being invisible!
The molecular structure of graphene differ from the other allotropes of carbon diamond and graphite in that graphene consist of a single layer of atoms.
It would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap."
graphene according to how much it can hold (calculator) and how dense it is.
no
No, not yet.
Yes Graphite is a MINERAL!!!!
