Sharaxaada
Shirkaddayadu waxay bixisaaDahaarka SiCadeegyada habka CVD ee dusha sare ee graphite, ceramics iyo alaabta kale, si gaasaska gaarka ah ee ay ku jiraan kaarboon iyo Silicon ay ka falceliyaan heerkulka sare si ay u helaan daahirsanaan sare SiC molecules, molecules lagu shubo dusha alaabta dahaarka ah, samaynta alakabka ilaalinta ee SiC.
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 xaalada koloriinaynta heerkulka sare.
3. Iska caabinta nabaadguurka: adkaanta sare, dusha sare, qaybo yaryar.
4. Iska caabinta daxalka: acid, alkali, milix iyo reagents organic.
