TheSilicon Carbide Dahaarka leh Warqadda EpitaxialIsku day in lagu isticmaaloQalabka Foornada Epitaxialoo ay samaysay Shiinaha Vet Energy, oo ka mid ah wax soo saarka iyo alaab-qeybiyeyaasha Shiinaha. IibsoSilicon Carbide Dahaarka leh Warqadda Epitaxialsaxaarad lagu isticmaalo gudaha ShiinahaQalabka Foornada Epitaxialqiimo jaban oo laga helo warshadeena. Waxaan leenahay summado noo gaar ah sidoo kale waxaan taageernaa tiro badan. Haddii aad xiisaynayso alaabtayada, waxaanu ku siin doonaa qiimo gorgortan. Ku soo dhawoow inaad iibsato alaab qiimo dhimis ah oo naga cusub oo tayo sare leh.
Shirkadeena waxay bixisaa adeegyada habka daahan SiC ee habka CVD ee dusha sare ee graphite, ceramics iyo alaabta kale, si gaasaska gaarka ah ee ay ku jiraan kaarboon iyo silikoon ay uga falceliyaan heerkulka sare si ay u helaan nadiifnimada sare ee SiC molecules, molecules deposited on the dusha alaabta dahaarka ah, samaynta lakabka ilaalinta 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.

Maxaad u dooran kartaa dhakhtarka xoolaha
1) waxaan haysanaa dammaanad saami oo nagu filan.
2) Baakadaha xirfadeed waxay hubisaa daacadnimada alaabta. Alaabta waxaa laguugu soo gudbin doonaa si badbaado leh.
3) kanaalo saadka oo badan ayaa suurtageliya in alaabta laguu keeno.
