Hoʻokaʻawale ʻia nā pahuhopu graphite i ka graphite isostatic a me ka graphite pyrolytic. E hoʻopuka ka mea hoʻoponopono o RSM i ka graphite pyrolytic i nā kikoʻī.
He ʻano mea kalapona hou ka Pyrolytic graphite. He kalapona pyrolytic ia me ka orientation crystalline kiʻekiʻe i waiho ʻia e ka mahu kemika ma ka graphite matrix ma 1800 ℃ ~ 2000 ℃ e ke kinoea hydrocarbon maʻemaʻe kiʻekiʻe ma lalo o kekahi kaomi umu. He kiʻekiʻe kiʻekiʻe (2.20g / cm³), maʻemaʻe kiʻekiʻe (maʻiʻo haumia (0.0002%)) a me anisotropy o ka thermal, uila, magnetic a me mechanical properties. ʻO ia hoʻi he mau waiwai like ʻole ma nā mokulele like ʻole. Ma ka mokulele C (ma kona mau papa) he haʻahaʻa haʻahaʻa haʻahaʻa, e hana ana ma ke ʻano he insulator. Ma ka mokulele AB (me nā papa) he kiʻekiʻe loa kona conductivity wela, e hana ana ma ke ʻano he alakaʻi maikaʻi loa. Loaʻa kā mākou pyrolytic graphite disc a me nā papa i ʻekolu mau mea like ʻole: Substrate Nucleated (PG-SN), Continuously Nucleated (PG-CN), a me High Conductivity Substrate Nucleated (PG-HT). Hoʻomau Nucleated (PG-CN) mea waiwai kino 15-20% kiʻekiʻe ma mua o ka Substrate Nucleated.Pyrolytic kalapona i hua i loko o fluidized moena ua nui hoʻohana 'ia no ka uhi 'ana i ka ili o nukelea wahie particles e pale leakage o fission huahana. Eia hou, ua hoʻohana 'ia e hana artificial kalapona waena kiwikā, lawe, a pela aku. metala maʻemaʻe, pulupulu no ka mea hoʻoponopono voltage, keʻena hoʻokuʻu o ka laser, mea hoʻokaʻawale wela no ka umu wela wela, pepa epitaxial no ka semiconductor. hana, etc.
