Graphite hom phiaj tau muab faib ua isostatic graphite thiab pyrolytic graphite.Tus editor ntawm RSM yuav qhia txog pyrolytic graphite kom meej.
Pyrolytic graphite yog ib hom tshiab ntawm cov khoom siv carbon.Nws yog ib qho pyrolytic carbon nrog siab crystalline orientation uas yog tso los ntawm cov tshuaj vapor ntawm graphite matrix ntawm 1800 ℃ ~ 2000 ℃ los ntawm siab purity hydrocarbon gas nyob rau hauv tej lub cub tawg siab.Nws muaj qhov ntom ntom (2.20g / cm³), siab purity (cov ntsiab lus impurity (0.0002%)) thiab anisotropy ntawm thermal, hluav taws xob, sib nqus thiab cov khoom siv tshuab.Nyob rau hauv lub dav hlau C (dhau ntawm nws cov khaubncaws sab nraud povtseg) nws muaj tsawg thermal conductivity, ua raws li ib tug insulator.Nyob rau hauv lub dav hlau AB (nrog rau cov khaubncaws sab nraud povtseg) nws muaj thermal conductivity heev, ua raws li ib tug superb conductor.Peb cov pyrolytic graphite discs thiab phaj muaj nyob rau hauv peb yam khoom sib txawv: Substrate Nucleated (PG-SN), Nruam Nucleated (PG-CN), thiab High Conductivity Substrate Nucleated (PG-HT).Nruam Nucleated (PG-CN) cov khoom muaj lub cev muaj zog 15-20% siab dua li ntawm Substrate Nucleated.Pyrolytic carbon uas tsim nyob rau hauv fluidized txaj yog tsuas yog siv rau txheej txheej ntawm cov khoom siv hluav taws xob los tiv thaiv cov khoom fission.Tsis tas li ntawd, nws kuj yog siv los ua cov pa roj carbon monoxide, cov kabmob, thiab lwm yam. Pyrolytic graphite tsim los ntawm lub txaj tsis fluidized yog siv rau hauv caj pas hauv ob sab phlu ntawm foob pob ua ntxaij nozzle, diamagnetic pob rau satellite cwj pwm tswj, electron tube grid, crucible rau smelting high- purity hlau, txhuam rau voltage regulator, paug chamber ntawm laser, thermal rwb thaiv tsev cov ntaub ntawv rau high-kub rauv, epitaxial ntawv rau semiconductor ntau lawm, thiab lwm yam.
