Cov pas nrig graphite rau cov khoom tsis yog hlau, ua cov txheej txheem txiav carbon arc gouging hauv cov khoom siv ua ntej vuam, yog ua los ntawm carbon, graphite ntxiv rau cov nplaum tsim nyog, los ntawm kev tsim extrusion, tom qab 2200℃ci tig tom qab plating ib txheej ntawm tooj liab thiab ua, kub tsis kam, hluav taws xob zoo conductivity, tsis yooj yim tawg, tsim rau txiav hlau rau hauv cov duab xav tau.
Cov pas nrig graphite feem ntau siv rau hauv lub cev cua sov ntawm cov cua sov kub siab, qhov kub siab tshaj plaws tuaj yeem ncav cuag 3000°C, nws yooj yim rau oxidize ntawm qhov kub siab, ntxiv rau lub tshuab nqus tsev, tsuas yog siv tau rau hauv huab cua nruab nrab lossis txo huab cua. Nws cov coefficient thermal expansion me me, cov thermal conductivity loj, cov coefficient tsis kam yog (8 ~ 13)× 10-6Ω ·m, qhov ua tau zoo dua li SiC, MoSi2 pas nrig, ua haujlwm kub siab, txias heev thiab ua haujlwm kub heev, tus nqi pheej yig dua.
Kev sib xyaw ua ke ntawm kub platinum thiab hlau. Cov yam ntxwv ntawm graphite: muaj zog tiv taus oxidation, tsis tshua muaj zog, siv tau kub txog li 1800 degrees Celsius thiab tiv taus corrosion.
Cov pas nrig graphite Muab cov pas nrig graphite, cov pas nrig graphite nias hauv av, cov pas nrig graphite nias isostatic, cov foob hiphite / carbon-graphite / carbon-graphite bearing / EDM graphite.
