Pyrolytic mpweya wokutirandi woonda wosanjikiza wapyrolytic carbon wokutidwapamwamba pa isostatic yoyeretsedwa kwambirigraphite pogwiritsa ntchito ukadaulo wa chemical vapor deposition (CVD). Ili ndi kachulukidwe kwambiri, kuyera kwambiri, komanso anisotropickutentha, magetsi, maginito, ndi makina.
Zofunika Kwambiri:
1. Pamwamba pake ndi wandiweyani komanso wopanda pores.
2. Kuyera kwambiri, zonyansa zonse <20ppm,mpweya wabwino.
3.Kukana kutentha kwakukulu, mphamvu imawonjezeka ndi kuwonjezeka kwa kutentha kwa ntchito, kufika pamwamba kwambirimtengo pa 2750 ℃, sublimation pa 3600 ℃.
4.Low zotanuka modulus, mkulu matenthedwe madutsidwe, otsika matenthedwe kukulitsa coefficient,ndi kukana kwambiri kutentha kwa kutentha.
5.Good mankhwala bata, kugonjetsedwa ndi asidi, alkali, mchere, ndi organic reagents, ndipo alipalibe chokhudza zitsulo zosungunuka, slag, ndi zinthu zina zowononga. Palibe oxidizekwambiri mu mlengalenga pansi pa 400 ℃, ndi mlingo makutidwe ndi okosijeni kwambirikuwonjezeka kwa 800 ℃.
6. Popanda kutulutsa mpweya uliwonse pa kutentha kwambiri, akhoza kukhala opanda vacuum wa10-7mmHg pafupifupi 1800 ℃.
Ntchito:
1. Kusungunula crucible kwa evaporation mumakampani a semiconductor.
2. Chipata champhamvu chamagetsi chamagetsi chamagetsi.
3. Burashi yomwe imalumikizana ndi chowongolera magetsi.
4. Graphite monochromator ya X-ray ndi nyutroni.
5. Mitundu yosiyanasiyana ya magawo a graphite ndikuyanika kwa chubu cha atomiki.
Pyrolytic carbon coating effect pansi pa maikulosikopu ya 500X, yokhala ndi malo osasunthika komanso osindikizidwa.
