Okuhlosiwe kwe-graphite kuhlukaniswe i-isostatic graphite ne-pyrolytic graphite.Umhleli we-RSM uzokwethula i-pyrolytic graphite ngokuningiliziwe.
I-Pyrolytic graphite iwuhlobo olusha lwe-carbon material.Ikhabhoni ye-pyrolytic ene-high crystalline orientation efakwa umhwamuko wamakhemikhali ku-graphite matrix ku-1800℃~2000℃ ngegesi ye-hydrocarbon ehlanzekile ngaphansi kwengcindezi ethile yesithando somlilo.Inokuminyana okuphezulu (2.20g/cm³), ukuhlanzeka okuphezulu (okuqukethwe ukungcola (0.0002%)) kanye ne-anisotropy yezinto ezishisayo, zikagesi, kazibuthe kanye nemishini.Lokhu kusho ukuthi inezakhiwo ezihlukene ezindizeni ezahlukene.Endizeni engu-C (kuzo zonke izendlalelo zayo) ine-conductivity ephansi ye-thermal, esebenza njenge-insulator.Endizeni ye-AB (enezendlalelo) inomoya oshisayo ophezulu kakhulu, osebenza njengomqhubi omuhle kakhulu.Amadiski ethu e-pyrolytic graphite namapuleti atholakala ngezinto ezintathu ezihlukene: I-Substrate Nucleated (PG-SN), I-Continuous Nucleated (PG-CN), kanye ne-High Conductivity Substrate Nucleated (PG-HT).I-Continuous Nucleated (PG-CN) impahla inezinto ezibonakalayo eziphakeme ngo-15-20% kunaleyo ye-Substrate Nucleated.Ikhabhoni ye-Pyrolytic ekhiqizwa embhedeni omanzi isetshenziswa kakhulu ukumboza ingaphezulu lezinhlayiya zamafutha enuzi ukuze kuvinjelwe ukuvuza kwemikhiqizo yokuqhekeka.Ngaphezu kwalokho, iphinde isetshenziselwe ukwenza i-artificial carbon center valve, i-bearing, njll. I-pyrolytic graphite ekhiqizwa umbhede ongamanzi isetshenziselwa ulwelwesi lomphimbo lwe-rocket nozzle, ibhola le-diamagnetic lokulawula isimo sesathelayithi, igridi ye-electron tube, crucible for smelting high- insimbi ehlanzekile, ibhulashi lesilawuli se-voltage, igumbi lokukhipha i-laser, izinto ezishisayo zokufakwa kwesithando somlilo esishisa kakhulu, ishidi le-epitaxial lokukhiqizwa kwe-semiconductor, njll.
