Njirimara nke Silicon Carbide:

-Njupụta dị ala

-Igwe ọkụ dị elu (nke dị nso na aluminom)

-Ezigbo nguzogide ujo thermal

-Mmiri mmiri na gas àmà

-High refractoriness (nwere ike ji mee ihe na 1450 ℃ na ikuku na 1800 ℃ na-anọpụ iche ikuku)

-Ọ naghị emebi ya site na corrosion ma ejikwala aluminom gbazere ma ọ bụ zinc gbazere mee mmiri

-Isi ike dị elu

-Ọnụọgụ esemokwu dị ala

-Nguzogide abrasion

-Na-eguzogide acid ndị bụ isi na ndị siri ike

-Enwere ike ihie ya

-Ike igwe dị elu

Ngwa Silicon Carbide:

-Njikọ na-atụgharị

-Semiconductor na mkpuchi

-Pmgbasa ozi Pump components

-Ihe mejupụtara kemịkalụ

-Igwefoto maka sistemu laser mmepụta ihe.

- Igwe ọkụ na-aga n'ihu na-erugharị, ndị na-agbanwe ọkụ, wdg.

Njirimara
A na-emepụta silicon carbide n'ụzọ abụọ:

1) Psịlịkọn carbide enweghị ntụkwasị obi

Mgbe ihe na-enweghị nrụgide sintered silicon carbide etched, ihe osise kristal n'okpuru 200X anya mikroskopu na-egosi na nkesa na nha nke kristal bụ otu, na kristal kasị ukwuu anaghị agafe 10μm.

2) Reaction sintered silicon carbide

Mgbe mmeghachi omume sintered silicon carbide kemịkalụ na-emeso akụkụ dị larịị ma dị nro nke ihe ahụ, kristal
Nkesa na nha n'okpuru microscope anya 200X bụ otu, yana ọdịnaya silicon efu anaghị agafe 12%.
