Ipuleti le-ceramic le-silicon carbide

Ezweni lokukhiqiza ngokunemba, kukhona into esekela buthule intuthuko yezimboni eziningi ezisezingeni eliphezulu - iqinile kunensimbi, imelana nokushisa kune-graphite, kodwa ihlala igcina umzimba ulula. Lokhu kunjalo.ipuleti le-ceramic le-silicon carbide, "i-metamaterial" ebalulekile embonini yanamuhla.
1, Izipho zemvelo kanye nokwakheka kokuhlakanipha komuntu
I-silicon carbide (SiC) akuyona into eyenzeka ngengozi elabhorethri. Kusukela ngo-1893, ososayensi bathola le minerali eyenzeka ngokwemvelo. Namuhla, ngokusebenzisa ubuchwepheshe bokwenziwa kwezinga lokushisa eliphezulu ukuhlanganisa kabusha isihlabathi se-silicon kanye nemithombo yekhabhoni emazingeni okushisa aphezulu, kudalwa izitsha zobumba ze-silicon carbide zezinga lezimboni ezisebenza kangcono. Lezi zinto zihlanganisa kahle ukuzinza kwezitsha zobumba nezici zama-semiconductor, zakha i-gene yezinto eziyingqayizivele.
2, Susa ukubhala phansi izinzuzo ezinhlanu eziyinhloko
1. Umnakekeli wokushisa okuphezulu
Ngaphansi kwezimo ezibucayi kakhulu zika-1350 ℃, izinsimbi ezivamile sezivele zithambile futhi zashintshashintsha, kuyilapho amapuleti e-silicon carbide ceramic esakwazi ukugcina ubuqotho besakhiwo. Lokhu kumelana nokushisa okuphezulu okungokwemvelo kwenza kube ukukhetha okuhle kakhulu kwezindawo ezifana nemishini yokuncibilikisa kanye nezinjini zezindiza.
2. Isivikelo esiqinile kakhulu
Ubulukhuni, obulandela idayimane kuphela, buvumela amapuleti e-silicon carbide ukuthi amelane kalula nokuguguleka kanye nomthelela wezinhlayiya zensimbi encibilikisiwe. Emgqeni wokubumba we-aluminium, isikhathi sayo sokuphila sandiswa izikhathi ezingaphezu kwezi-5 uma kuqhathaniswa nezinto zendabuko zokuphikisa.
3. Unekhono ekuqhubeni ukushisa
Ngokungafani nezakhiwo "zokuvikela" ze-ceramics ezivamile, i-silicon carbide ceramics inomoya omuhle kakhulu wokushisa. Le nto "ephefumulayo" ingadlulisa ukushisa ngokushesha ngenkathi igcina ukuzinza kwayo, okwenza isebenze kahle kakhulu emkhakheni wokushabalalisa ukushisa kwe-semiconductor.

4. Iphayona Elilula
Ngamandla afanayo, isisindo sayo siyingxenye eyodwa kwezintathu kuphela kunesensimbi. Lesi sici "sokuphakamisa izinto ezisindayo kalula" siletha izixazululo zokunciphisa isisindo eziphumelelayo emasimini afana nemishini emisha yamandla kanye nokuhamba ngesitimela.
5. Umvikeli Wamakhemikhali
Njengoba ibhekene nemidiya egqwala kakhulu, izitsha zobumba ze-silicon carbide zibonisa ukuzinza okumangalisayo. Ku-reactor yamakhemikhali, kufana nomqaphi ongalokothi ugqwale, oqinisekisa ukuphepha kokukhiqiza.
3, Amathuba angenamkhawulo okushintsha ikusasa
Kusukela ku-substrate ethwala umthwalo yamaseli e-photovoltaic kuya ezingxenyeni ezingagugi zemishini enembile, kusukela kusisekelo sokushisa sama-semiconductor chips kuya kumojuli yokuhlunga yemishini yokuvikela imvelo, amapuleti e-silicon carbide ceramic achaza kabusha imingcele yokusebenza kwezinto zezimboni. Emasimini abalulekile njengamandla amasha, ulwazi lwe-elekthronikhi, kanye nemishini ephezulu, izinto ze-silicon carbide ceramic ziqhuba ukuthuthukiswa kwezimboni buthule.
Njengomsunguli wezobuchwepheshe ohileleke kakhulu emkhakheni wezinto zobumba ezikhethekile, sihlala sizibophezele ekuqhubekiseleni phambili ukusebenza kwezinto ze-silicon carbide ngokweqile. Ngokuqhubeka nokuthuthukisa izinqubo zokusila kanye namasu okwelapha ubuso, ibhodi ngalinye lobumba liba umsebenzi wobuciko wezimboni ongamelana novivinyo lwesikhathi. Ikusasa selifikile, ake sibone ndawonye ubuhle obuyingqayizivele bezinto zobumba ze-silicon carbide eziqhakaza emasimini amaningi.
I-Shandong Zhongpeng ihlala inamathela emcabangweni wokuthi “ukusungula izinto ezintsha kuqhuba intuthuko yezimboni”, futhi ilangazelela ukusebenza nabalingani bomhlaba wonke ukuhlola amathuba okusetshenziswa angenamkhawulo e-silicon carbide ceramics.
