Cimriga dheer SIC kuleyliyaha dahaarka garaafka loogu talagalay MOCVD K465i, kuleyliyaha garaafka

Kuleyliyaha garaafiga ee cimri-dheer ee SIC ee loogu talagalay MOCVD K465i

Sharaxaad Gaaban:

Qaybaha kuleyliyaha garaafka waxaa loo isticmaalaa foornada heerkul sare oo heerkulku gaaray 2200 darajo deegaanka faakuumka iyo 3000 digrii ee deoxidized iyo deegaanka gaaska la geliyo.
Tilmaamaha ugu muhiimsan ee kuleyliyaha garaafka:
1. isku mid ahaanshaha qaab dhismeedka kuleylka.
2. koronto wanaagsan iyo culeys koronto oo sarreeya.
3. iska caabin daxalka.
4. oksidizability.
5. nadiifinta kiimikada sare.
6. xoogga farsamada sare.
Faa'iidada waa tamar hufan, qiimo sare iyo dayactir hooseeya.
Waxaan soo saari karnaa ka-hortagga oksaydhka iyo cimriga dheer ee garaafiga crucible, caaryada garaafka iyo dhammaan qaybaha kuleyliyaha garaafka.
