Ua vaevaeina sini graphite i le isostatic graphite ma le pyrolytic graphite.O le faatonu o le RSM o le a faʻalauiloaina faʻamatalaga pyrolytic graphite.
Pyrolytic graphite o se ituaiga fou o mea carbon.O se kaponi pyrolytic ma tulaga tioata maualuga o loʻo teuina e le vailaʻau vailaʻau i luga o le graphite matrix i le 1800 ℃ ~ 2000 ℃ e ala ile kasa hydrocarbon mama maualuga i lalo ole mamafa o le ogaumu.E i ai le maualuga maualuga (2.20g / cm³), maualuga le mama (mea le mama (0.0002%)) ma anisotropy o mea vevela, eletise, mageta ma masini. O lona uiga e eseese mea totino i luga o vaalele eseese.I le vaalele C (i luga o ona laulau) o loʻo i ai le maualalo o le vevela, e galue o se insulator.I le va'alele AB (fa'atasi ai ma fa'avae) o lo'o i ai le maualuga o le fa'auluina o le vevela, e fai ma ta'avale sili.O matou pyrolytic graphite discs ma plates e maua i mea eseese e tolu: Substrate Nucleated (PG-SN), Continuously Nucleated (PG-CN), ma High Conductivity Substrate Nucleated (PG-HT).Fa'aauau Nucleated (PG-CN) mea e iai mea fa'aletino 15-20% maualuga atu nai lo le Substrate Nucleated.Pyrolytic carbon gaosia i le moega fluidized e masani lava ona fa'aaogaina mo le ufiufi o luga o mea faaniukilia suauu e puipuia le leakage o fission oloa.E le gata i lea, o loʻo faʻaaogaina foi e fai ai le gaogao tutotonu o le carbon, tauaveina, ma isi. Pyrolytic graphite gaosia e le moega e le faʻafefeteina o loʻo faʻaaogaina mo le faʻaʻaʻau o le pusi roketi, polo diamagnetic mo le amio satelite, laina eletise eletise, faʻafefe mo le faʻafefe maualuga- uamea mama, pulumu mo le faatonutonuina voltage, potu lafoai o le laser, mea faʻavela vevela mo ogaumu vevela maualuga, pepa epitaxial mo le gaosiga semiconductor, ma isi.
