i-silicon carbide metal

I-Silicon Carbide Metal: IsiKhokelo esiBanziISilicon carbide (SiC) sisixhobo esimangalisayo esinoluhlu olubanzi lwezicelo, ezidla ngokubizwa ngokuba i-silicon carbide metal, nangona ngokobugcisa yi-ceramic. Esi sikhokelo sijonga kwiipropati, iindlela zokuvelisa, kunye nokusetyenziswa okuhlukeneyo kwesi sixhobo somelele.

Ukuqonda iSilicon Carbide

Iipropati ze Silicon Carbide Metal

Silicon carbide metal, ekwabizwa ngokuba yi-carborundum, inobunzima obukhethekileyo, okwesibini emva kwedayimani. Obu bunzima bugqithileyo, budityaniswa ne-thermal conductivity ephezulu, ukunganyangeki kweekhemikhali, kunye namandla angaphezulu, kuyenza ilungele izicelo ezibango. Iqondo layo eliphezulu lokunyibilika (malunga ne-2730 ° C) liqhubela phambili lifaka isandla ekulufanelekeni kwayo kwiindawo ezinobushushu obuphezulu. Isakhiwo esikhethekileyo sekristale se-SiC siphumela kwiipolymorphs ezahlukeneyo, nganye ibonisa iipropati ezahlukeneyo, ezikhokelela kwizicelo ezilungiselelwe ngokuxhomekeke kuhlobo oluthile lwe-SiC esetyenzisiweyo. Ezi propati zenza ukuba ifaneleke ngokukodwa kwiindidi ezahlukeneyo zezicelo kumashishini amaninzi.

Iindlela zeMveliso

Imveliso ye i-silicon carbide metal ibandakanya iindlela ezininzi, ngokukodwa inkqubo ye-Acheson, esebenzisa ukushisa okuphezulu ukusabela i-silica (SiO2) kunye nekhabhoni (C) kwisithando sombane se-arc. Ezinye iindlela ziquka i-chemical vapor deposition (CVD) kunye nobuchule boxinzelelo oluphezulu oluvumela ukuveliswa kweekristale ze-SiC ezicocekileyo ezisetyenziswa kwizicelo eziphezulu. Indlela ethile esetyenzisiweyo ixhomekeke kubunyulu obufunwayo kunye nesakhiwo sekristale semveliso yokugqibela, izinto ezichaphazelayo njengeendleko kunye nesicelo.

Usetyenziso lwe Silicon Carbide Metal

Izicelo zoShishino

Icandelo lezoshishino lisetyenziswa kakhulu i-silicon carbide metal kwizicelo ezininzi. Ukuqina kwayo kuyenza ibe yeyona nto ibalulekileyo kwizixhobo ezirhabaxa, amavili okusila nakwizixhobo zokusika. I-inertness yekhemikhali ibaluleke kakhulu kwizicelo ezifana ne-crucibles yobushushu obuphezulu kunye ne-linings ye-reactors yamachiza. Ukongezelela, ukukwazi ukumelana neemeko ezigqithisileyo zifumana izicelo kwiinkqubo ezahlukeneyo zamashishini apho ukuqina kunye nokuchasana kubaluleke kakhulu.

Usetyenziso lwe-elektroniki

Inkqubela yakutshanje yenziwe i-silicon carbide metal umdlali ophambili kwishishini le-elektroniki. Iimpawu ezikhethekileyo ze-elektroniki ze-SiC zivumela ukudala amandla aphezulu, izixhobo eziphezulu ze-frequency ezifana ne-transistors kunye ne-diode. Ezi zixhobo ziya zibaluleke kakhulu kumbane we-elektroniki, zibonelela ngeenzuzo ezibalulekileyo ekusebenzeni ngokufanelekileyo kunye nokusebenza xa kuthelekiswa nezinto zemveli ezisekelwe kwi-silicon. Oku kwenza i-SiC ibaluleke kakhulu kwizicelo ezifana neenqwelo zombane, iinkqubo zamandla ahlaziyekayo, kunye nezixhobo zamashishini ezinamandla amakhulu. I-Inner Mongolia Xinxin Silicon Industry Co., Ltd.https://www.xinxinsilicon.com/) ngumzekelo ohamba phambili wenkampani ebandakanyekayo ekuveliseni nasekuboneleleni ngezinto eziphezulu ze-SiC zezicelo ezinjalo.

Ezinye ii-aplikeshini

Ngaphandle kokusetyenziswa kweshishini kunye ne-elektroniki, i-silicon carbide metal ifumana indlela yayo kwamanye amacandelo awohlukeneyo. I-biocompatibility yayo yenza ukuba ifaneleke kwizicelo ezithile ze-biomedical, ngelixa ukumelana nokushisa kwayo kunye namandla kuxhatshazwa kwizicelo eziphezulu zokushisa njengezinto eziphikisayo kunye neengubo zokukhusela.

Ukuthelekisa iSiC nezinye izinto

Le theyibhile ilandelayo iyathelekisa i-silicon carbide metal nezinye izinto eziqhelekileyo:

Ukuqukumbela

Silicon carbide metal yimathiriyeli eguquguqukayo nesebenza kakhulu enoluhlu olubanzi lwezicelo kumashishini awohlukeneyo. Ukudityaniswa kwayo okukodwa kweepropathi kuyenza ibaluleke kakhulu kwinkqubela phambili yetekhnoloji kunye neenkqubo zoshishino. Njengoko uphando luqhubeka kunye neendlela zokuvelisa ziphucula, ikamva libambe amandla amakhulu ngakumbi kule nto iphawulekayo.Qaphela: Idatha ekwitheyibhile engentla iqikelelwe kwaye inokwahluka ngokuxhomekeke kwibakala elithile kunye nenkqubo yokuvelisa. Ulwazi oluthe vetshe kwiipropathi ezithile zemathiriyeli ye-SiC eyahlukeneyo inokufunyanwa ngoncwadi lwenzululwazi kunye nedatha yedatha evela kubaboneleli abanje nge-Inner Mongolia Xinxin Silicon Industry Co., Ltd.
