Kedu ihe bụ mkpuchi SiC?

Ihe mkpuchi SiC bụ mkpuchi mkpuchi silicon carbide siri ike, nke nwere nnukwu corrosion na nguzogide okpomọkụ yana ezigbo ikuku ọkụ. A na-eji mkpuchi SiC a dị elu dị ọcha na semiconductor na ụlọ ọrụ eletrọnịkị iji chebe ndị na-ebu wafer, ntọala na ihe ndị na-ekpo ọkụ site na gburugburu ndị na-emebi emebi na nke na-emeghachi omume. Ihe mkpuchi SiC dịkwa mma maka ọkụ ọkụ na ikpo ọkụ nlele na oghere dị elu, reactive na ikuku oxygen.

Njirimara anụ ahụ nke mkpuchi SiC na-egosipụtakarị na nguzogide okpomọkụ ya dị elu, ike siri ike, nguzogide corrosion na ọkụ ọkụ.

Paragraf anụ ahụ a na-ahụkarị na-abụkarị ndị a:

Isi ike: Ihe mkpuchi SiC na-enwekarị ike ike Vickers na oke nke 2000-2500 HV, nke na-enye ha oke oke iyi na nguzogide mmetụta na ngwa mmepụta ihe.

Njupụta: Ihe mkpuchi SiC na-enwekarị njupụta nke 3.1-3.2 g/cm³. Nnukwu njupụta na-enye aka na ike ọrụ na ịdịte aka nke mkpuchi.

Thermal conductivity: Ihe mkpuchi SiC nwere ihe nrụpụta okpomọkụ dị elu, nke na-adịkarị na 120-200 W / mK (na 20 ° C). Nke a na-enye ya ezigbo conductivity thermal na gburugburu okpomọkụ dị elu ma mee ka ọ dị mma maka ngwa ọgwụgwọ okpomọkụ na ụlọ ọrụ semiconductor.

Ebe mgbaze: silicon carbide nwere ebe mgbaze nke ihe dịka 2730 Celsius ma nwee nkwụsi ike nke okpomọkụ na oke okpomọkụ.

Ọnụọgụ nke Thermal Mgbasawanye: SiC mkpuchi nwere ọnụ ala linear ọnụọgụ nke thermal mgbasa (CTE), a na nso nke 4.0-4.5 µm / mK (na 25-1000 ℃). Nke a pụtara na nkwụsi ike nke akụkụ ya dị mma karịa nnukwu ọdịiche okpomọkụ.

Nguzogide corrosion: Ihe mkpuchi SiC na-eguzogide nke ukwuu na corrosion na acid siri ike, alkali na oxidizing gburugburu, karịsịa mgbe ị na-eji acids siri ike (dị ka HF ma ọ bụ HCl), nkwụsị nke corrosion ha karịrị nnọọ nke ihe ígwè.

Enwere ike itinye mkpuchi SiC na ihe ndị a:
