Sharaxaada
Shirkaddayadu waxay bixisaaDahaarka SiCadeegyada habka dusha sare ee graphite, ceramics iyo qalabka kale ee habka CVD, si gaasas gaar ah oo ay ku jiraan kaarboon iyo Silicon falcelin karaan heerkulka sare si ay u helaan-nadiifinta sare Sic molecules, kaas oo lagu shubo karaa on dusha alaabta dahaarka ah si ay u sameeyaan alakabka ilaalinta ee SiCfoosto epitaxy nooca hy pnotic.
Tilmaamaha ugu muhiimsan
1. Iska caabbinta oksaydhka heerkulka sare:
caabbinta oksaydhisku weli aad bay u wanaagsan tahay marka heerkulku uu gaadho 1600 C.
2. Nadiifin sare: oo ay samaysay uumiga kiimikaad ee hoos yimaada xaalad koloriineed heerkul sare ah.
3. Iska caabinta nabaadguurka: adkaanta sare, dusha sare, qaybo yaryar.
4. Iska caabinta daxalka: acid, alkali, milix iyo reagents organic.
