Sharaxaad:
Silicon Carbide waxay leedahay hanti aad u fiican oo adkaysi u leh, awood farsamo oo sarreeya, kulaylka kuleylka sarreeya, is-saliid wanaagsan oo loo isticmaalo sidii wejiyaal shaabad leh, biraha iyo tuubooyinka hawada sare, mashiinnada, birta, daabacaadda iyo midabaynta, cuntada, dawooyinka, warshadaha baabuurta iyo wixii la mid ah on. Marka wejiyada sic ah lagu daro wejiyada graphite khilaafku waa kan ugu yar waxaana laga samayn karaa shaabad farsamo oo awood u leh inay ku shaqeeyaan shuruudaha shaqada ee ugu sarreeya.
Guryaha Aasaasiga ah ee Silicon Carbide:
- Cufnaanta hoose
Heerarka kulaylka sare (oo u dhow aluminium)
- Iska caabbinta shoogga kulaylka wanaagsan
-Cadaynta dareeraha iyo gaaska
Refractoriness sare (waxaa loo isticmaali karaa at 1450 ℃ hawada iyo 1800 ℃ in jawi dhexdhexaad ah)
-Ma laha daxalka oo ha ku qoysin aluminium dhalaalay ama zinc dhalaalay
-Adayg sare
-Isku-xidhnaanta hoose
-Abrasion caabbinta
-Waxay u adkaysataa asiidhyada aasaasiga ah iyo kuwa xoogga leh
-La-daran karo
-Awoodda farsamada sare
Codsiga Silicon Carbide:
-Shabaado makaanikada ah, biraha, riixitaanka, iwm
-Goobaha wareega
-Semiconductor iyo dahaarka
-Waxyaabaha matoorka suufka
-Qaybaha kiimikada
-Muraayadaha nidaamyada laser warshadaha.
- Reactors-socod joogto ah, kulaylka beddelayaasha, iwm.
Muuqaal
Silicon carbide waxaa loo sameeyaa laba siyaabood:
1) Silicon carbide sinteed aan cadaadis lahayn
Ka dib markii walxaha silikoon carbide sinteed aan cadaadis la saarin, jaantuska wejiga crystal ee hoos yimaada 200X mikroskoobku wuxuu muujinayaa in qaybinta iyo cabbirka kiristaalo ay isku mid yihiin, crystal-ka ugu weyna kama badna 10μm.
2) Kaarbiide silikoon oo falcelin ah
Ka dib falcelinta sinteed carbide silikoon kiimiko ah waxay daawaysaa qaybta siman oo siman ee walxaha, crystal
Qaybinta iyo cabbirka hoos yimaada mikroskoob ee 200X waa lebbis, iyo waxa ku jira silikoon bilaash ah kama badna 12%.
