Silicon karbide isahani

Mwisi yisi yubukorikori bwuzuye, hariho ibikoresho bishyigikira bucece iterambere ryinganda nyinshi zo murwego rwohejuru - birakomeye kuruta ibyuma, birwanya ubushyuhe kuruta grafite, ariko burigihe bigumana umubiri woroshye. Ubu nisilicon karbide isahani, “metamaterial” y'ingirakamaro mu nganda zigezweho.
1 gifts Impano za kamere hamwe no gutegera ubwenge bwabantu
Carbide ya Silicon (SiC) ntabwo ari ibicuruzwa bitunguranye muri laboratoire. Nko mu 1893, abahanga bavumbuye iyi myunyu ngugu isanzwe. Muri iki gihe, ukoresheje tekinoroji yubushyuhe bwo hejuru kugirango wongere uhuze umucanga wa silicon nisoko ya karubone mubushyuhe bwinshi, urwego rwinganda rwa silicon karbide ceramics hamwe nibikorwa byiza birashirwaho. Ibi bikoresho bihuza neza ituze ryubutaka hamwe nibiranga semiconductor, bikora gene idasanzwe.
2 Kuramo ibyiza bitanu byingenzi
1. Kurinda ubushyuhe bwo hejuru
Mugihe gikabije cya 1350 ℃, ibyuma bisanzwe bimaze koroshya no guhinduka, mugihe plaque ceramic ceramic silicon irashobora gukomeza ubusugire bwimiterere. Uku kuvuka kwinshi kurwego rwo hejuru bituma ihitamo neza kumirima nkibikoresho byo gushonga na moteri yindege.
2. Ingabo ikomeye yo gukingira
Ubukomezi, ubwa kabiri nyuma ya diyama, butuma amasahani ya karubide ya silicon irwanya byoroshye isuri ningaruka ziterwa nicyuma gishongeshejwe. Kumurongo wa aluminium, igihe cyacyo cyongerewe inshuro zirenga 5 ugereranije nibikoresho gakondo.
3. Abahanga mu gutwara ubushyuhe
Bitandukanye n’imiterere ya "insulation" yubukorikori busanzwe, silicon karbide ceramics ifite amashanyarazi meza. Ibi bikoresho "bihumeka" birashobora kohereza vuba ubushyuhe mugihe bigumye bihagaze neza, bigatuma bikora neza mubijyanye no gukwirakwiza ubushyuhe bwa semiconductor.

4. Umupayiniya woroheje
Ku mbaraga zimwe, uburemere bwacyo ni kimwe cya gatatu cyicyuma. Ibi biranga "guterura ibintu biremereye" bizana ibisubizo bigabanya kugabanya imirima nkibikoresho bishya byingufu hamwe na gari ya moshi.
5. Kurinda imiti
Guhura nibitangazamakuru byangirika cyane, silicon carbide ceramics yerekana ituze ritangaje. Muri reaction ya chimique, ni nkumurinzi utigera ubora, ukingira umutekano.
3 possibilities Ibishoboka bitagira ingano byo guhindura ejo hazaza
Kuva kuri substrate yikoreza imitwaro ya selile yifotora kugeza ibice bidashobora kwangirika byimashini zisobanutse neza, kuva aho ubushyuhe bwo gukwirakwiza ubushyuhe bwa chipi ya semiconductor kugeza kuri module yo kuyungurura ibikoresho byo kurengera ibidukikije, plaque ceramic silicon karbide isobanura imipaka yimikorere yibikoresho byinganda. Mubikorwa byingenzi nkingufu nshya, amakuru ya elegitoroniki, nibikoresho byo mu rwego rwo hejuru, ibikoresho bya ceramic silicon karbide bigenda byicecekera kuzamura inganda.
Nkumuhanga mu ikoranabuhanga wagize uruhare runini mubijyanye nubutaka bwihariye, duhora twiyemeje gusunika imikorere yibikoresho bya karibide ya silicon bikabije. Mugukomeza kunoza uburyo bwo gucumura hamwe nubuhanga bwo kuvura hejuru, buri kibaho cyibumba gihinduka ibihangano byinganda bishobora kwihanganira ikizamini cyigihe. Ejo hazaza haraho, reka duhamirize hamwe igikundiro kidasanzwe cya silicon carbide ceramics zimera mumirima myinshi.
Shandong Zhongpeng ahora yubahiriza igitekerezo cy "guhanga udushya bitera iterambere mu nganda", kandi ategerezanyije amatsiko gukorana n’abafatanyabikorwa ku isi kugira ngo bashakishe uburyo butagira ingano bwakoreshwa mu gukora ubukerarugendo bwa silicon karbide.
