1. A refactories: graphite ma ana oloa i ai meatotino o le maualuga vevela teteʻe ma maualuga malosi. I metallurgical alamanuia, e masani ona faʻaaogaina e fai ai grafite ipu. I le faia o uamea, e masani ona faʻaaogaina le graphite e fai ma sui puipuia mo le uʻuina o uʻamea ma le ufiufi o le ogaumu ogaumu.
2. O ni mea taua: i le eletise alamanuia, e faʻaaogaina e fausia ai electrodes, pulumu, carbon rods, carbon tubes, positive electrodes of mercury positive current device, graphite gaskets, telefoni vaega, coatings o TV ata paipa, ma isi.
3. E pei o ofu-teteʻe mea faʻasili o le faʻaaogaina o ofu: o le graphite e masani ona faʻaaogaina o mea e faʻamalulu ai i masini masini. Lubricating suauʻu e le mafai ona faʻaaogaina i se saoasaoa maualuga, maualuga le vevela ma le maualuga o le mamafa, ae o le grafite ofuina-tetee mea e mafai ona galue i le 200 ~ 2000 鈩 ma maualuga sliding saosaoa e aunoa ma lubricating suauʻu. Tele meafaigaluega faʻasalalauina auala leaga o lautele faia lautele o mea kalafi, e pei o piston ipu, faʻamau faʻamau ma le fanauina. Latou te le tau faʻaopopoina le faʻaaluina o le suauʻu i le taimi o faʻagaioiga. O le emulsion o le Graphite o se suauʻu lelei foi mo le tele o metotia gaʻoa (uaea ata, paipa ata).
4. E iai le mautu lelei o vailaʻau ile Graphite. Graphite ina ua maeʻa faʻapitoa gaioiga ei ai uiga o le pala, tetee lelei conductivity vevela ma maualalo permeability. E lautele faʻaaogaina i le faia o vevela fesuiaʻiga, tali atu tane, condensers, susunuina 'olo, mitiia' olo, faʻamalama, faʻavevela, faʻamama ma pamu. Lautele faaaogaina i petrochemical, hydrometallurgy, acid-faavae gaosiga, gaosia alava, pepa ma isi alamanuia vaega, mafai ona sefe le tele o uamea mea.
5. Faʻaaogaina pei o le lafoina, oneone liliu, oti lafo ma maualuga-vevela metallurgical mea: ona o le laʻititi coefficient o vevela faʻalautelega o grafite ma lona mafai gafatia vave maluluina ma vevela faʻamamaina, grafite mafai ona faʻaaogaina o se suia mo glassware. A maeʻa ona faʻaaogaina le graphite, e mafai ona maua mai i le uʻamea ma le saʻo o le lapoʻa, lamolemole luga ma le maualuga o fua, e mafai ona faʻaaogaina e aunoa ma le faʻagaoioia poʻo sina faʻagaoioiga, ma sefe ai le tele o uʻamea. I le gaosiga o sima kareti sima ma isi paʻu metallurgy gaioiga, e masani ona faʻaaogaina mea kalafi e fai ai mamanu ma poselane vaʻa mo le gaosiga. O le faʻaola laʻau faʻavela ole ipu faʻaitumalo, o mea lagolago ma mea faʻamama o le monocrystalline silicon e faia uma i le maualuga o le kalafi. I se faʻaopopoga, graphite mafai foi ona faʻaaogaina o le graphite faʻaʻesega laupapa ma faʻavae mo lagona gaogao smelting, maualuga vevela teteʻe ogaumu ogaumu, tootoo, ipu, grid ma isi vaega.
6. Faʻaaogaina i atomika malosiaga alamanuia ma le atunuʻu puipuiga alamanuia: graphite ei ai le lelei neutron retarder, lea e faʻaaogaina i atomic reactor. O le reactor o le uranium graphite o se ituaiga o le atomic reactor o loʻo faʻaaogaina lautele i le taimi nei. O le decelerating mea na faʻaaogaina i le malosiaga eletise reactor e tatau ona i ai le maualuga liusuavai tulaga, mautu ma le pala tetee. E mafai e le Graphite ona faʻamalieina aiaiga o loʻo i luga. O le mama aʻiaʻi o le kalafi faʻaaogaina i le atomic reactor e matua maualuga lava, ma o mea le mama e le tatau ona sili atu i le fiasefulu o ppm. Ae maise lava ole boron mea e tatau ona laʻititi ifo ile 0.5ppm. I le puipuiga o le atunuʻu alamanuia, kalafi o loʻo faʻaaogaina foi e fai ai mausali roketi nozzles, missile cones isu, aerospace meafaigaluega vaega, vevela mea faʻaʻesega ma aneti radiation mea.
7. E mafai foi e le Graphite ona puipuia le faʻapuna mai le palaka. O suʻega o vaega talafeagai e faʻaalia ai o le faʻaopopoina o le aofaʻi o paʻu kalafi i totonu o le vai (e tusa ma le 4 ~ 5g i tone tone o le vai) e mafai ona puipuia le faʻapuna mai le palaka. I se faʻaopopoga, ufiufi ufiufi luga uʻamea chimney, taualuga, alalaupapa ma paipa mafai puipuia le pala ma ele.
8. E mafai ona faʻaaogaina le Graphite e fai ma penitala, penivali ma polesi sooupu. Ina ua maeʻa faʻapitoa faʻagasologa, kalafi mafai ona faia i ni vaega faʻapitoa faapitoa ma faʻaaogaina i talafeagai alamanuia matagaluega.
9. Eletise: faʻafefea mafai ona fesuiaʻi graphite apamemea pei electrode
