  1. Amioga vevela
    • Tu'umea kalafifa'aalia lelei le fa'auluina o le vevela, fa'amautinoa le tufatufaina atu o le vevela. O lenei meatotino e faʻaitiitia ai le vevela ma faʻamautinoa e oʻo lava i le liusuavai, ma faʻamalosia lelei mo metala pei o auro, kopa, ma alumini.
    • E mafai ona o'o atu le tau o le fa'avevela e o'o atu i le 100 W/m·K, lea e sili atu pe a fa'atusatusa i mea fa'apolopolo masani.
  2. Tete'e maualuga-Sua
    • Tu'umea kalafie mafai ona tatalia le maualuga o le vevela, e oo atu i le 1700°Ci le ea lemu po'o tulaga gaogao. Ole mea lea e mafai ai ona latou fa'amauina le fa'atonuina o le fa'atulagaina i totonu o siosiomaga faigata e aunoa ma le fa'aleagaina.
    • O lo'o tumau pea le mautu ma e mafai ona fa'aleagaina i lalo ole vevela tele.
  3. Maualalo Coefficient o le fa'alauteleina o le vevela
    • O mea fa'akalafi e iai amaualalo coefficient o le faalauteleina vevela(i lalo ifo o le 4.9 x 10^-6 /°C), fa'aitiitia ai le ono ta'e po'o le te'i vevela pe a fa'aalia i suiga vave o le vevela.
    • O le vaega lea e fa'aigoa fa'apitoa ai fa'ameamea fa'akalafi mo fa'agasologa e aofia ai le fa'avevela faifaipea ma le fa'alili.
  4. Tete'e a'e
    • O le graphite e le aoga ma ofo maimaualuga tete'e i le tele o acids, alkalis, ma isi mea corrosive, aemaise i le faʻaitiitia poʻo le le mautonu o le ea. O le mea lea e fa'amalieina ai u'amea graphite mo si'osi'omaga fa'ama'i fa'amalosi i le u'amea po'o le fa'amamaina.
    • O mea e tetee atu i le faʻamaʻiina e mafai ona faʻaleleia atili e ala i paʻu poʻo togafitiga faʻapitoa, faʻamautinoa le umi o le ola tautua.
  5. Fa'aeletise Fa'atonu
    • I le avea ai o se taʻavale lelei o le eletise, o mea graphite e talafeagai mo faʻaoga faʻamafanafana. Ole maualuga ole eletise e mafai ai ona faʻapipiʻi lelei ma faiga faʻapipiʻi, faʻamautinoaina le vevela vave ma le tutusa.
    • O lenei meatotino e sili ona aoga i faiga e manaʻomiau'amea fa'avevela afi, fa'aleleia le fa'atinoina o galuega i alamanuia e pei o galuega faufale po'o metallurgy.
  6. Mama ma Meafaitino
    • Tu'u'amea graphite sili ona mama(e oo atu i le 99.9% mama) e taua mo talosaga e tatau ona aloese ai mai le faaleagaina o uamea, e pei o le gaosiga o uʻamea taua poʻo sima maualuga.
    • Silicon carbide graphite cruciblestu'ufa'atasia mea totino uma o le graphite ma le silicon carbide, ofoina atu le fa'aleleia atili o le malosi fa'ainisinia, fa'ama'i fa'ama'i, ma le maualuga o le liusuavai, e talafeagai mo tulaga ogaoga o galuega.
  7. Malosi ma le Umi
    • Tu'umea graphite oomi fa'aisostaticallyo lo'o gaosia ina ia maua ai le toniga tutusa ma le malosi, e mafua ai le umi o le ola ma fa'aitiitia mea fa'aletonu i le taimi o galuega maualuga-vevela. O nei u'amea e sili atu foi ona tetee atu i le tafia ma le faaleagaina o masini.

  8. Fa'aaogāga vaila'au:

    • kaponi (C): 20-30%
    • Silicon Carbide (SiC): 50-60%
    • Alumina (Al2O3): 3-5%
    • O isi: 3-5%
  9. Laisene ma Fa'atusa
    • E maua a matou ipu graphite i le tele o lapopo'a ma fa'atulagaga. Maiu'amea laiti graphite(talafeagai mo su'ega u'amea lapo'a su'esu'e) i u'amea lapopo'a ua fuafuaina mo le fa'ameamea fa'a alamanuia, matou te ofoina atu fofo fa'apitoa mo talosaga uma.
    • Tu'u fa'alava fa'akalafima u'amea masasaa faufaue mafai foi ona faʻapipiʻiina i manaʻoga faʻapitoa e tuʻuina atu, faʻamautinoa le faʻaogaina ma le lelei i le faʻaogaina o uʻamea.
