Cubic Silicon Carbide (β-SiC)
Cubic Silicon Carbide (β-SiC)
Cubic silicon carbide yumbu foda foda ne mai launin toka-kore. Its sinadaran kwayoyin dabara ne: SiC, kwayoyin nauyi 40.10, yawa 3.2g/cm3, narkewa batu 2973 ℃, thermal fadada coefficient 2.98×10-6K- 1.
Silicon carbide yumbu foda yana da babban tsarki, kunkuntar girman girman rabo, ƙananan pores, babban aikin sintiri, tsarin crystal na yau da kullum, kyakkyawan yanayin zafi, kuma shine semiconductor wanda zai iya tsayayya da hadawan abu da iskar shaka a yanayin zafi; β-SiC whiskers suna da tsayi Large diamita rabo, high surface gama, high diamita rabo, da kuma low barbashi abun ciki a cikin whiskers, da yi shi ne mafi alhẽri daga wasu ko an immersed a cikin wani m yanayi, musamman abrasive masana'antu da ma'adinai, ko fallasa zuwa yanayin zafi wuce 1400 ° C. Samfuran yumbu ko ƙarfe na ƙarfe na kasuwanci, gami da gawawwakin zafin jiki na ultrahigh.

Babban amfani da silicon carbide: Xinli Abrasive na iya samar da siliki carbide don amfani iri-iri, gami da hexagonal ko rhombohedral α-SiC da cubic β-SiC da β-SiC whiskers. Haɗaɗɗen kayan da aka haɗa da silicon carbide da robobi, karafa, da yumbu na iya haɓaka kaddarorinsa daban-daban. Saboda girman kwanciyar hankali na thermal, babban ƙarfi, da haɓakar yanayin zafi, ana amfani dashi sosai a cikin kayan makamashin atomic, na'urorin sinadarai, sarrafa zafin jiki, da kayan lantarki da na lantarki. , Semiconductor filin, lantarki dumama aka gyara da resistors, da dai sauransu Har ila yau, ana iya amfani da abrasives, abrasive kayan aikin, ci-gaba refractory kayan, da lafiya yumbu.
Silicon carbide na cubic yana ba da kewayon aikace-aikace a cikin masana'antu da yawa, musamman a cikin manyan kayan lantarki, na'urorin RF, lantarki mai ƙarfi, na'urori masu ɗaukar hoto, yanayin zafi mai zafi, firikwensin, da optoelectronics.
