Global production of natural graphite in 2021 was over a billion tonnes. China produces almost 80% of that, with the rest coming mostly from Brazil, Turkey, and India.
In 1779, scientists determined that the material they had previously thought was lead was actually a form of microcrystalline carbon that they named graphite (from the Greek "graphein" meaning "to write"). Graphite is one of the three natural forms of pure carbon—the others are coal and diamond.

Comb-like 3D natural graphite anodes are fabricated via a low temperature direct write 3D technology. • 3D-printed graphite anodes have thickness of 347.3, 581.7 and 786.7 μm and areal mass loading reaches 16.3, 24.4 and 32.9 mg cm −2.. The 3D-printed graphite anode display high areal capacities and stable cycling performance.
Graphite is a naturally occurring modification of carbon (chemical formula: C). Its atoms arrange themselves in the hexagonal pattern, which is typical for carbon, and thus form a hexagonal layered lattice. Graphite gets its typical grey color from its opaque grey to black crystals. See more
Graphite. Graphite is a soft, black, metallic mineral composed of the element carbon.It is nontoxic and rubs off easily on rough surfaces, which is why graphite mixed with fine clay, rather than actual lead, is used to make pencil leads.The word graphite derives from the Greek gr é phein, to write or draw.. Graphite has the same chemical …
Most of the graphite consumed in the U.S. in 2018 was synthetic graphite, with 63% of this graphite produced domestically. Production of synthetic graphite emits more greenhouse gases than mining natural graphite (Natural graphite has between 62% and 89% lower greenhouse gas emissions). Synthetic graphite is also more expensive.
flake graphite production is very small, in the +200-mesh range. North America produced only 4% of the world's graphite supply with production in Canada and Mexico. No production of natural graphite was reported in the United States, but two companies were developing graphite projects—one in Alabama and one in Alaska.
Graphite is a critical mineral for lithium-ion batteries, and its battery demand is expected to grow ten-fold by 2030. Meeting this increasing demand will require a higher supply of both natural graphite and its synthetic counterpart. However, graphite's entire supply chain is heavily reliant on China, which makes it vulnerable to disruptions ...
The three pieces—the black lead and the two halves of wood—were glued together with the black lead inside. The result was a rectangular writing implement and the world's first wooden pencils ...
Natural graphite is a mineral form of graphitic carbon. It varies considerably in crystallinity. Most of the commercial graphite is mined and usually contains other minerals. ... The word graphite is from the Greek language which translates as 'to write'. So the most common use of graphite is in making the lead in pencils. This lead is a ...
