Dahaarka CVD-SiC wuxuu leeyahay astaamo qaab-dhismeed isku mid ah, walxo isku dhafan, iska caabin heerkul sare, iska caabin oksaydh, daahirnimo sare, iska caabin aashito iyo alkali iyo falgal dabiici ah, oo leh sifooyin jireed iyo kiimiko oo deggan.

Marka la barbardhigo walxaha graphite-ka ee saafiga sare leh, graphite-ku wuxuu bilaabaa inuu oksaydheeyo 400C, taasoo sababi doonta luminta budada oksaydheynta awgeed, taasoo keenta wasakhowga deegaanka ee aaladaha durugsan iyo qolalka faakiyuumka, waxayna kordhisaa wasakhda deegaanka ee saafiga sare leh.

Si kastaba ha ahaatee, dahaarka SiC wuxuu ilaalin karaa xasilloonida jireed iyo kiimikada 1600 digrii. Waxaa si weyn loogu isticmaalaa warshadaha casriga ah, gaar ahaan warshadaha semiconductor-ka.

Shirkaddayadu waxay bixisaa adeegyada habka dahaarka SiC iyadoo la adeegsanayo habka CVD ee dusha sare ee garaafitka, dhoobada iyo agabyada kale, si gaasaska gaarka ah ee ka kooban kaarboon iyo silikoon ay uga falceliyaan heerkulka sare si ay u helaan molecules-ka SiC ee saafiga ah, molecules-ka lagu shubo dusha sare ee agabka dahaarka leh, iyagoo sameeya lakab ilaalin SIC ah. SIC-ga la sameeyay si adag ayuu ugu xiran yahay saldhigga garaafitka, isagoo siinaya sifooyin gaar ah saldhigga garaafitka, sidaas darteedna wuxuu ka dhigayaa dusha sare ee garaafitka mid is haysta, aan lahayn porosity, iska caabin heerkul sare, iska caabin daxaleed iyo iska caabin oksaydh.

Codsiga:

Astaamaha ugu muhiimsan:

1. Iska caabinta oksaydhka heerkulka sare:

Iska caabbinta oksaydhku wali aad bay u fiican tahay marka heerkulku gaaro 1700 C.

2. Nadiifnimo sare: waxaa lagu sameeyaa kaydka uumiga kiimikada iyadoo xaalad koloriin heerkul sare leh.

3. Iska caabbinta nabaad-guurka: adkaansho sare, dusha sare oo is haysta, walxo yaryar.

4. Iska caabbinta daxalka: aashitada, alkali, milixda iyo walxaha dabiiciga ah.
