Kana simbi iri musimboti weindasitiri, saka pane chinhu chakafanana ne "nhumbi dzisingaonekwe" dzeindasitiri - chinyararire chinotsigira mashandiro ezvitofu zvinopisa zvakanyanya, chinodzivirira hupenyu hwemidziyo chaiyo, uye chinotogadzira nzira yekutanga kwemachipisi e semiconductor. Chinhu ichi ndechesilicon carbide zvedongo, basa guru rave rakadzika midzi muindasitiri yechinyakare kwemakore zana uye rakavandudzwa munguva itsva.
'Mudziviriri weTembiricha' muMakilns eIndasitiri
Padivi pechoto chinoputika chiri mufekitari yekunyungudutsa simbi uye mukati mechoto chinotenderera chiri mufekitari yesimende, zviuru zvemadhigirii ekupisa zvinotakura magasi anoparadza uye kutenderera, zvichiita kuti zvinhu zvesimbi zvechinyakare zviwanzo "kundikana" pano. Zviumbwa zvesilicon carbide zvave chinhu chinodiwa kune zvikamu zvepakati zvakaita semachira echoto uye zvinopisa nekuda kwekudzivirira kwavo kupisa kwakanyanya (zvinokwanisa kutsungirira tembiricha iri pamusoro pe1350 ℃ kwenguva yakareba), pamwe ne "simba razvo rakaoma" mukudzivirira kupisa uye kuramba ngura. Kuvapo kwazvo kwawedzera kutenderera kwekushanda kwemachoto eindasitiri kakawanda uye kwakaderedza zvakanyanya kushandiswa kwesimba, inova nharaunda diki yekuvandudza mhando uye kushanda zvakanaka mukugadzira kwechinyakare.
'Geni rehupenyu hurefu' remidziyo yemakanika
Uchifamba mukamuri repombi yechero fekitari yemakemikari, unogona kuona "mufananidzo" wesimbi dzesilicon carbide. Panyaya yekutakura maacid akasimba, maalkali akasimba, kana zvinhu zvine zvidimbu, mhete dzesimbi dzakagadzirwa nesilicon carbide dzinogona kunzi "mambo wekugara kwenguva refu" - kuomarara kwadzo kuri kwechipiri kune dhaimani, kuramba kwadzo kupfeka kwakapetwa kagumi pane kwesimbi dzakaoma, uye dzinogara pamwe chete nemakemikari akawanda. Hunhu uhwu hunowedzera kutenderera kwekugadzirisa michina yakakosha kubva pamwedzi yakati wandei kusvika kumakore akati wandei, zvichideredza zvakanyanya mari yekushanda nekugadzirisa yeindasitiri dzechinyakare dzekugadzira.
Rwendo rwekuyambuka miganhu kubva kune zvechinyakare kusvika kune zvechizvino-zvino
Kana zviumbwa zvesilicon carbide zvikasangana nematekinoroji ari kubuda, simba rinoburitswa harina fungidziro:
Kugadzira Semiconductor: Zviumbwa zvesimbi zvesilicon carbide zvakagadziriswa nenzira dzakakosha zvave chinhu chakakosha pakugadzira crystal polishing mukugadzira chips, uye nanoscale flatness yavo inoita kuti machines akagadzirwa nemazvo.
Shanduko Itsva yeSimba: Muindasitiri ye photovoltaic, zvigadziko zve silicon carbide ceramic zvinobatsira mukukura kwe monocrystalline silicon; Mundima yesimba re hydrogen, se fuel cell bipolar plate material, iri kukurudzira kushandiswa kwesimba rakachena.
Midziyo yemazuva ano: Munyaya dzekudzivirira mabara, zviumbwa zvesilicon carbide zviri kupindura kurudziro isingaperi yekudzivirira kuchengetedzeka neruzha rwazvo rwakasiyana, uye kugadzikana kwazvo munzvimbo dzakaoma kuri kuramba kuchiwedzera miganhu yemaindasitiri evanhu.
Kufemerwa kweChidimbu cheCeramic
Nyaya yesimbi yesilicon carbide inoratidza mafungiro ekushanduka-shanduka kwezvinhu zvemaindasitiri: zvinhu zvakanaka kwazvo hazvimbokanganisi, asi zvinogonesa. Zvinogona kuramba zviripo kwemakore zana, uye zvinovhura mikana mitsva mumunda wemachipisi. Kuchinjika uku kunopfuura nguva kunosimbisa chokwadi chiri nyore - kufambira mberi kwezvinhu zvepakutanga ndiko kunonyanya kukosha pakuvandudza maindasitiri.
Sekambani yave ichibatanidzwa zvakanyanya mubasa rezvigadzirwa zvesimbi zvesimbi kweanopfuura makore gumi, tinogara tichitenda kuti kudzima moto kwese muchoto, kushanda kwakasimba kwemidziyo yese, uye kuberekwa kwakakwana kwechipu chimwe nechimwe zvinoratidza simba rekuvandudzwa kwezvinhu. Uye zvigadzirwa zvesimbi zvesimbi zvesimbi zvesimbi zvesimbi zvinoratidza simba iri muindasitiri.
