2004/8/19Structure of graphite and its intercalation compounds In 1859 Benjamin Brodie noted the highly lamellar structure of thermally reduced graphite oxide.[20] [21] In 1916, Peter Debije and P. Scherrer determined the structure of graphite by powder X-ray diffraction. [22] [23] [24] The structure was studied in more detail by V. Kohlschtter and P. Haenni in 1918, who also described the

Expandable graphite

To produce expandable graphite, natural graphite flakes are treated in a bath of acid and oxidizing agent.Usually used oxidizing agents are hydrogen peroxide, potassium permanganate or chromic acid. Concentrated sulphuric acid or nitric acid are usually used as the compound to be incorporated, with the reaction taking place at temperatures of 30 C to 130 C for up to four hours.

Graphite pencil

A graphite pencil, also called a lead pencil, is a type of pencil in which a thin graphite core is embedded in a shell of other material. The pencil shell is mostly wooden, but can be made of plastic or recycled paper. History A large deposit of graphite was discovered in 1565 on the approach to Grey Knotts from the hamlet of Seathwaite in Borrowdale parish, Cumbria, England.

Graphit – Wikipedia

Graphit (auch Grafit) ist ein sehr hufig vorkommendes Mineral aus der Mineralklasse der „Elemente". Er ist eine der natrlichen Erscheinungsformen des chemischen Elements Kohlenstoff in Reinform und kristallisiert uerlich gesehen im hexagonalen Kristallsystem (genaueres siehe Kristallstruktur). Graphit bildet undurchsichtige, graue

Grafiet

Grafiet is een allotrope vorm van het element koolstof. Grafiet is een van de zachtste vaste elementaire materialen. De kristalstructuur is hexagonaal. Als allotroop van koolstof heeft grafiet een aantal opmerkelijke eigenschappen voor een niet-metaal. Zo is het een relatief goede elektrische geleider.

Graphic design

Graphic design is the art, profession and academic discipline whose activity consists in projecting visual communications intended to transmit specific messages to social groups, with specific objectives. Therefore, it is an interdisciplinary branch of design whose foundations and objectives revolve around the definition of problems and the determination of objectives for decision-making

Ziemia – Wikipedia, wolna encyklopedia

Ziemia oraz pozostałe planety Układu Słonecznego powstały 4,54 0,05 mld lat temu z mgławicy słonecznej – obłoku gazu i pyłu, ktry podczas powstawania Słońca przekształcił się w dysk. Z owego dysku miały powstać wszystkie planety oraz planetoidy.

Graphite bomb

A graphite bomb is intended to be a non-lethal weapon used to disable an electrical grid.The bomb works by spreading a dense cloud of extremely fine, chemically treated carbon filaments over air-insulated high voltage installations like transformers and power lines, causing short-circuits and subsequent disruption of the electricity supply in an area, a region or even an entire small country.

1. Mining of Graphite Natural graphite is not very plentiful. Carbon forms strong bonds with oxygen in carbon monoxide and especially carbon dioxide i.e. it oxidises easily. Nevertheless natural deposits do exist, and artificial graphite can be made in large quantities.
