Kuleyliyeyaasha Dahaarka leh ee Silicon Carbide SiC

Sharaxaad Gaaban:

Kuleyliyaha carbide Silicon waxaa dahaarka leh oksaydh bir ah, in uu yahay, fog infrared rinjiga Silicon carbide saxan sida element shucaac ah, in godka element (ama jeexdin) galay silig kuleyliyaha koronto, in hoose ee saxan carbide silikon gelin dahaarka qaro weyn, refractory. , Walxaha kuleylka kuleylka, ka dibna lagu rakibo qolofka birta ah, terminaalka waxaa loo isticmaali karaa in lagu xiro qalabka korontada.

Marka shucaaca infrared-ka fog ee kuleyliyaha carbide silikoon uu u soo baxo shayga, wuu nuugi karaa, wuu milicsan karaa oo wuu dhex mari karaa. Walxaha la kululeeyay iyo kuwa la qalajiyey waxay nuugaan tamarta shucaaca fog ee infrared qoto dheer oo ka mid ah unugyada gudaha iyo dusha sare isla mar ahaantaana, soo saara saameyn is-kuleyl ah, si dareeraha ama molecules biyuhu ay uumi u baxaan oo u kululaadaan si siman, sidaas darteed ka fogaanshada qallafsanaanta iyo isbeddelka tayada leh. sababtoo ah heerarka kala duwan ee balaadhinta kulaylka, si muuqaalka maaddada, sifooyinka jireed iyo farsamada, xajinta iyo midabka ayaa weli ah.

Sharaxaada

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.
