Graphite /ˈɡræfaɪt/, archaically referred to as Plumbago, is a crystalline form of carbon, a semimetal, a native element mineral, and one of the allotropes of carbon. Graphite is the most stable form of carbon under standard conditions. Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds. Graphite may be considered the highest grade of coal, just above anthracite and alternatively called meta-anthracite, although it is not normally used as fuel because it is difficult to ignite.
There are three principal types of natural graphite, each occurring in different types of ore deposit:

It morphs into coal, diamond, graphite, graphene, fullerenes, nanotubes, buckyballs and more, all with their own set of fantastic properties. Except for CO2, that causes global warming. But graphite is awesome!

Using a microwave to expand graphite produces partially-exfoliated graphene "worms" that are useful in the production of graphene and for making supercapacitor batteries. This method involves microwaving acid-treated graphite to produce expanded graphite. Acid-treated graphite can be made by soaking approximately 10 grams of ~35 mesh flake graphite in 150 mL concentrated sulfuric acid (H2SO4, 98%) together with 50 mL 70% Phosphoric acid (70%) overnight. The acid molecules are small enough to squeeze in between and intercalate the layers of graphene that make up the graphite flakes. The graphite is then placed in a acid-resistant filter paper (PE/PTFE) and washed with copious amounts of deionized (DI) or distilled water several times to remove any excess acid until the pH reaches 7 and is d...

Light from pencil lead - Graphite Lamp Graphite combustion reaction: C + O2 = CO2 Graphite is poorly conductive substance. Current flows through graphite. With graphite resistance 0.019 Ω, begins to heat up, and then burn. Electrical energy is changed into heat energy by sending electromagnetic waves. When metal atoms are introduced by heating in a state of agitation, then emit radiation at different wavelengths. This is a radiation covering a broad frequency range, the spectral maximum in the range attributable to the higher frequency (shorter wavelength), the higher the temperature of the body. A man sees a wave with a frequency of 1014 - 1015Hz. What happens to the graphite in the presented video: - A hot graphite emits light due to the flow of electric current. - Electricity goes i...
In the gleaming nightfall we can watch the light retreat.
Its rays slither eastward, like snakes along the grass,
As it leaves us to ourselves.
Woods of tall trees
Old, deformed and barren - obscuring the sun -
Red and tired
From working its way up from life giver
To massive hydrogen bomb
We can't see the sun,
But we can see the god rays surrounding the trees
And brief dim flickers of light shining through them.
These are rays from a god that is long dead.
It's our final night in this place.
There is no tomorrow.
