insimbi ye-silicon carbide

I-Silicon Carbide Metal: I-Comprehensive GuideI-Silicon carbide (SiC) iyimpahla emangalisayo enezinhlobonhlobo zezinhlelo zokusebenza, ezivame ukubizwa ngokuthi insimbi ye-silicon carbide, nakuba ngokobuchwepheshe kuyi-ceramic. Lo mhlahlandlela ubheka izici, izindlela zokukhiqiza, kanye nokusetshenziswa okuhlukahlukene kwalokhu okuqinile.

Ukuqonda i-Silicon Carbide

Izakhiwo ze I-Silicon Carbide Metal

I-silicon carbide metal, eyaziwa nangokuthi i-carborundum, inobunzima obungavamile, isibili ngemva kwedayimane. Lobu bunzima obedlulele, obuhambisana nokuguquguquka kwe-thermal okuphezulu, ukungabi namandla kwamakhemikhali, namandla aphakeme, kuyenza ilungele izinhlelo zokusebenza ezinzima. Indawo yayo yokuncibilika ephezulu (engaba ngu-2730°C) iphinde ibe nomthelela ekufanelekeni kwayo kwezindawo ezinezinga eliphezulu lokushisa. Isakhiwo sekristalu esiyingqayizivele se-SiC siphumela kuma-polymorphs ahlukahlukene, ngalinye libonisa izakhiwo ezihluke kancane, okuholela ekusetshenzisweni okuhambisanayo kuye ngohlobo oluthile lwe-SiC esetshenzisiwe. Lezi zakhiwo ziyenza ifaneleke ngokuhlukile ezinhlobonhlobo zezinhlelo zokusebenza kuzo zonke izimboni eziningi.

Izindlela Zokukhiqiza

Ukukhiqizwa kwe insimbi ye-silicon carbide kuhilela izindlela eziningana, ngokuyinhloko inqubo ye-Acheson, esebenzisa amazinga okushisa aphezulu ukuze asabele i-silica (SiO2) kanye ne-carbon (C) esithandweni somlilo se-arc kagesi. Ezinye izindlela zifaka i-chemical vapor deposition (CVD) nezindlela zokucindezela okuphezulu ezivumela ukukhiqizwa kwamakristalu e-SiC ahlanzekile asetshenziswa ezinhlelweni ezithuthukisiwe. Indlela eqondile esetshenziswayo incike ekuhlanzekeni okufiswayo kanye nesakhiwo sekristalu somkhiqizo wokugcina, okunomthelela ezintweni ezifana nezindleko nokusetshenziswa.

Izicelo ze I-Silicon Carbide Metal

Izicelo zezimboni

Umkhakha wezimboni usebenzisa kakhulu insimbi ye-silicon carbide ezinhlelweni eziningi. Ukuqina kwayo kuyenza ibe ingxenye ebalulekile kumathuluzi abrazayo, amasondo okugaya namathuluzi okusika. Ukungangeni kwamakhemikhali kubalulekile ezinhlelweni ezinjengama-crucibles anezinga lokushisa eliphezulu nama-linings kuma-reactor amakhemikhali. Ukwengeza, ikhono layo lokumelana nezimo ezimbi kakhulu lithola ukusetshenziswa ezinqubweni ezihlukahlukene zezimboni lapho ukuqina nokumelana kubaluleke kakhulu.

Izicelo zikagesi

Intuthuko yakamuva yenziwe insimbi ye-silicon carbide umdlali obalulekile embonini yezogesi. Izakhiwo ze-elekthronikhi eziyingqayizivele ze-SiC zivumela ukwakhiwa kwamandla aphezulu, amadivaysi asebenza kakhulu njengama-transistors nama-diode. Lezi zingxenye ziya ngokuya zibaluleke kakhulu kugesi wamandla, zinikeza izinzuzo ezibalulekile ekusebenzeni kahle nokusebenza uma kuqhathaniswa nezingxenye zendabuko ezisekelwe ku-silicon. Lokhu kwenza i-SiC ibaluleke kakhulu ezinhlelweni ezifana nezimoto zikagesi, izinhlelo zamandla avuselelekayo, kanye nemishini yezimboni enamandla amakhulu. I-Inner Mongolia Xinxin Silicon Industry Co., Ltd.https://www.xinxinsilicon.com/) uyisibonelo esihamba phambili senkampani ehilelekile ekukhiqizeni nasekunikezeni izinto ze-SiC ezisezingeni eliphezulu zezicelo ezinjalo.

Ezinye izinhlelo zokusebenza

Ngaphandle kokusetshenziswa kwezimboni kanye ne-elekthronikhi, insimbi ye-silicon carbide ithola indlela yayo kweminye imikhakha eyahlukene. I-biocompatibility yayo iyenza ifaneleke kwezinye izinhlelo zokusebenza ze-biomedical, kuyilapho ukumelana nokushisa kwayo namandla kusetshenziswa izinhlelo zokusebenza ezishisa kakhulu ezifana nezinto eziphikisayo nezingubo zokuzivikela.

Ukuqhathanisa i-SiC nezinye Izinto

Ithebula elilandelayo liyaqhathanisa insimbi ye-silicon carbide nezinye izinto ezijwayelekile:

Impahla	I-Silicon Carbide	I-aluminium oxide	I-Tungsten Carbide
Ukuqina (isikali se-Mohs)	9.5	9	9-10
I-Thermal Conductivity (W/mK)	120-390	30-40	50-60
I-Melting Point (°C)	~ 2730	2050	~ 2870

Isiphetho

I-silicon carbide metal iwumsebenzi oguquguqukayo futhi osebenza kakhulu one-spectrum ebanzi yokusetshenziswa kuzo zonke izimboni ezihlukahlukene. Inhlanganisela yayo eyingqayizivele yezakhiwo iyenza ibaluleke kakhulu ekuthuthukisweni okuningi kwezobuchwepheshe nezinqubo zezimboni. Njengoba ucwaningo luqhubeka nezindlela zokukhiqiza ziba ngcono, ikusasa linamandla amakhulu kakhulu ale nto ephawulekayo.Qaphela: Idatha esethebula elingenhla iyalinganiselwa futhi ingahluka kuye ngebanga elithile kanye nenqubo yokukhiqiza. Ulwazi olwengeziwe mayelana nezakhiwo ezithile zezinto ezihlukahlukene ze-SiC lungatholakala ngemibhalo yesayensi nemininingwane yedatha evela kubahlinzeki abafana ne-Inner Mongolia Xinxin Silicon Industry Co., Ltd.
