graphite (mineral) (mineral, inorganic material, ... Materials (hierarchy name)) |
|
Note: Naturally occurring crystalline form of carbon dimorphous with diamond. Graphite has a layered structure that consists of rings of six carbon atoms arranged in widely spaced horizontal sheets, and thus crystallizes in the hexagonal system, in contrast to the same element crystallizing in the octahedral or tetrahedral system as diamond, resulting in very different characteristics in each. Graphite is opaque, soft, greasy to the touch, and iron black to steel gray in color; it occurs as crystals, flakes, scales, veins, bedded masses, or disseminations in metamorphic rocks. |

Dutch ..... Een in de natuur voorkomende gekristalliseerde vorm van koolstof, dimorf met diamant. Grafiet heeft een gelaagde structuur die bestaat uit ringen met zes koolstofatomen die zijn gerangschikt in horizontale lagen die relatief ver van elkaar af liggen, en kristalliseert in het zesvlakkige systeem, anders dan diamant, waarbij koolstofatomen kristalliseren in het achtvlakkige of viervlakkige systeem. Hierdoor hebben diamant en grafiet zeer verschillende eigenschappen. Grafiet is ondoorzichtig en zacht, voelt vettig aan en is ijzerzwart tot staalgrijs van kleur; het komt voor als kristallen, vlokken, schilfers, aders, bodemlagen of verspreid in metamorfe gesteenten. |
Spanish ..... Forma de carbono cristalina que existe en la naturaleza dimorfo con el diamante. Es opaco, blanco, graso al tacto y de color negro hierro a gris acero. Se encuentra como cristales, copos, escamas, venas, masas embutidas o diseminado en rocas metamórficas. |
