PROPERTIES AND CHARACTERISTICS OF GRAPHITE
graphite and other manufactured graphite properties and how they are tested has also grown. It is with this thought in mind that this primer on properties and characteristics of graphite was developed. POCO, now owned by Entegris, has been a supplier Compressive Strength to the semiconductor industry for more than 35 years.
Thermal properties of graphite- thermal expansion ...
The interatomic spacing between the carbon atoms of graphite is a function of temperature. At 0 K, these atoms have their lowest energy position or ground state. The increased energy resulting from increasing temperature causes the atoms to vibrate and move further apart. In other words, the mean interatomic spacing increases and the result is thermal expansion.
HEAT TREATMENT OF GRAPHITE AND RESULTING TRITIUM …

Raman spectroscopy of graphene and graphite: …
1-7-2007 · We review recent work on Raman spectroscopy of graphite and graphene. We focus on the origin of the D and G peaks and the second order of the D peak. The G and 2 D Raman peaks change in shape, position and relative intensity with number of graphene layers. This reflects the evolution of the electronic structure and electron–phonon interactions.

About Graphite | Next Source
Graphite is in a much stronger position than lithium carbonate as it is the anode material of choice for most battery designs. The anode requires a porous carbon material and graphite is the optimum match.
Carbon - Wikipedia
Carbon (from Latin: carbo "coal") is a stone element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent stone bonds.It belongs to group 14 of the periodic table. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a half-life of about 5,730 years.

Russia plans to significantly strengthen its position in the global graphite market in the coming years, through the increase of production of both traditional crystalline and cryptocrystalline graphite, along with the more valuable isostatic graphite.
Graphene - Wikipedia
Graphene / ˈ ɡ r æ f iː n / is an allotrope of carbon consisting of a single layer of atoms in a two-dimensional honeycomb lattice in which one atom occupies each vertex.. The name is a contraction of "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers. The fused six-atom benzene rings are a basic structural feature ...
