Hawsha ugu weyn ee kaarboonka pyrolytic ee dahaarka sare ee nadiifka ah ee giraanta adag ee dahaarka leh waa in la bixiyo waxqabadka xidhidhiyaha wanaagsan iyo ilaalinta kulaylka.Waxaa loo isticmaali karaa qalab heerkul sare oo kala duwan iyo hababka, sida foornooyinka heerkulka sare, gubanaya, unugyada habka petrochemical, iwm Maaddadu waxay si wax ku ool ah u go'doomin kartaa oo ka hortagtaa daadinta gaasaska heerkulka sare, dareeraha ama adkaha, waxayna iska caabin kartaa daxalka kiimikada iyo xidho
Daahan kaarboon pyrolytic waa lakab khafiif ah oo kaarboon pyrolytic ah oo dahaarka dusha sare ee isostatic aadka loo sifeeyay.graphite iyadoo la isticmaalayo tignoolajiyada kaydka uumiga kiimikada (CVD).Waxay leedahay cufnaan sare, nadiif sare, iyo anisotropickuleyl, koronto, magnetic, iyo sifooyinka farsamada.
Tilmaamaha ugu muhiimsan:
1. Dushu waa cufan oo aan lahayn daloolno.
2. Nadiifin sare, wadarta guud ee wasakhda <20ppm,hawo wanaagsan.
3.Iska caabin heerkul sarreeya, xooggu wuxuu kordhiyaa heerkulka isticmaalka oo sii kordhaya, isagoo gaarey kan ugu sarreeyaqiimaha at 2750 ℃, sublimation at 3600 ℃.
4.modules laastikada hoose, conductivity kaamerada sare, coefficient hoose ballaarinta kulaylka,iyo iska caabin shoog kulayl oo aad u fiican.
5.Degenaansho kiimikaad oo wanaagsan, adkaysi u leh aashitada, alkali, cusbada, iyo reagents organic, oo lehwax saameyn ah kuma laha biraha dhalaaliyay, dharbaaxada, iyo warbaahinta kale ee daxalka leh.Ma oxidizesi aad ah jawiga ka hooseeya 400 ℃, iyo heerka oksaydhisku si weynkor u kaca 800 ℃.
6. Adigoon wax gaas ah ku sii dayn heerkul sare, waxay ilaalin kartaa faakuumka10-7mmHg qiyaastii 1800 ℃.
Codsiga wax soo saarka:
1. Qulqulka dhalaalay ee uumiga gudahawarshadaha semiconductor.
2. Albaabka tuubada elektarooniga ah ee awoodda sare leh.
3. caday oo la xidhiidha maamulaha danabka.
4. monochromator graphite ee raajada iyo neutronka.
5. Qaabab kala duwan oo ah substrates graphite iyodahaarka tuubada nuugista atomiga.
Saamaynta dahaarka kaarboonka ee pyrolytic ee hoos imanaya mikroskoob 500X ah, oo leh dusha aan qummanayn oo xidhan.
