Silicio karbidas (SiC) suk\u0117l\u0117 didel\u0119 bang\u0105 galios elektronikos srityje. SiC geb\u0117jimas atlaikyti auk\u0161t\u0105 \u012ftamp\u0105 leid\u017eia jam pakeisti silic\u012f prietaisuose, kuriuose reikia didesnio efektyvumo ir galios tankio, nes \u0161i med\u017eiaga pasi\u017eymi keliomis unikaliomis savyb\u0117mis.<\/p>\n
Silicio karbidas yra itin kieta ir a\u0161tri abrazyvin\u0117 med\u017eiaga, tod\u0117l ji idealiai tinka sausam ir \u0161lapiam \u0161lifavimui, pavyzd\u017eiui, medin\u0117ms grindims \u0161lifuoti arba r\u016bdims i\u0161 metalo \u0161alinti; be to, j\u0105 taip pat galima naudoti marmurui ir akmens skulpt\u016broms poliruoti.<\/p>\n
Kadangi j\u012f galima naudoti \u012fvairiems metalams ir lydiniams, \u012fskaitant juod\u0105j\u012f, spalvot\u0105j\u012f ir aliumin\u012f, jis puikiai tinka metalografijai. D\u0117l savo kietumo ir konsistencijos jis puikiai tinka ruo\u0161ti bandinius mikroskopiniam tyrimui.<\/p>\n
Silicio karbido \u0161vitrinis popierius b\u016bna \u012fvairaus gr\u016bd\u0117tumo, kad b\u016bt\u0173 galima pa\u0161alinti \u012fvairius pavir\u0161iaus netobulumus ir juos i\u0161lyginti; stambaus gr\u016bd\u0117tumo \u0161vitrinis popierius tinka \u0161iurk\u0161tiems pavir\u0161iams \u0161lifuoti, o smulkesnio gr\u016bd\u0117tumo - i\u0161lyginti. Silicio karbido \u0161vitrinis popierius \u0161iandien yra vienas i\u0161 pla\u010diausiai naudojam\u0173 \u0161vitrinio popieriaus tip\u0173; be daugelio kit\u0173 paskir\u010di\u0173, jis naudojamas medin\u0117ms grindims atnaujinti, metalin\u0117ms detal\u0117ms nuvalyti, r\u016bdims i\u0161 automobili\u0173 dali\u0173 pa\u0161alinti, grindims atnaujinti, sur\u016bdijusioms automobili\u0173 detal\u0117ms nuvalyti arba metaliniams komponentams nuvalyti. Gaminamas reaguojant polisiloksanams \u012f silicio karbido miltelius greitai, ta\u010diau be joki\u0173 pastang\u0173, kad b\u016bt\u0173 gautas itin auk\u0161tos kokyb\u0117s galutinis produktas, kur\u012f galima labai greitai ir lengvai pristatyti!<\/p>\n
Silicio karbidas pasi\u017eymi puikiu atsparumu dilimui ir ma\u017eu \u0161iluminiu pl\u0117timusi, tod\u0117l yra puiki med\u017eiaga apdirbimo operacijoms. D\u0117l savo ilgaam\u017ei\u0161kumo jis taip pat yra populiarus kaip \u0161lifavimo med\u017eiaga lapidaryje, o \u0161lifavimo diskams, pjovimui vandens srove, rutuliukams ir keramikai naudojamas jo kietumas ir atsparumas cheminiam poveikiui.<\/p>\n
Varis pasi\u017eymi i\u0161skirtiniu 9 Mohso kietumo laipsniu; kartu su atsparumu korozijai ir dilimui jis yra ne\u012fkainojama med\u017eiaga \u012frankiams ir \u012frangai, naudojamai su metalin\u0117mis ir nemetalin\u0117mis med\u017eiagomis, pavyzd\u017eiui, keramika, stiklu ir ugniai atspariomis plytomis.<\/p>\n
SiC yra vis populiaresn\u0117 med\u017eiaga, naudojama elektros prietaisuose, ypa\u010d galios puslaidininkiuose, pavyzd\u017eiui, IGBT ir bipoliniuose tranzistoriuose, nes pasi\u017eymi auk\u0161ta pramu\u0161imo \u012ftampa, greitu perjungimo laiku ir ma\u017eesne \u012fjungimo var\u017ea nei alternatyvios technologijos. Be to, d\u0117l trinties \u0161ilum\u0105 i\u0161skirian\u010di\u0173 savybi\u0173 ji tinka ir greitaeigiams guoliams bei siurbli\u0173 velen\u0173 sandarikliams.<\/p>\n
Silicio karbido \u0161vitrinis popierius yra ne\u012fkainojamas automobili\u0173 k\u0117bulo darb\u0173 ir restauravimo s\u0105jungininkas: nuo formavimo ir i\u0161lyginimo stambesnio gr\u016bd\u0117tumo \u0161vitriniu popieriumi, da\u017eymo ar da\u017eymo smulkesnio gr\u016bd\u0117tumo \u0161vitriniu popieriumi iki tobulos drob\u0117s da\u017eymui ar da\u017eymui suk\u016brimo smulkesnio gr\u016bd\u0117tumo \u0161vitriniu popieriumi - taip u\u017etikrinamas kiekvienos detal\u0117s tobulumas.<\/p>\n
Silicio karbido kietumas pagal Moso skal\u0119 yra 9,1, tod\u0117l jis yra viena i\u0161 kie\u010diausi\u0173 \u0161iuo metu prieinam\u0173 abrazyvini\u0173 med\u017eiag\u0173 - su juo savo patvarumu var\u017eosi tik deimantas ir boro karbidas.<\/p>\n
SiC keramin\u0117s med\u017eiagos pla\u010diai naudojamos kompozitin\u0117se med\u017eiagose, pavyzd\u017eiui, anglies pluo\u0161tu sustiprintame silicio karbide (CFRC), dilimui atspariose automobili\u0173 stabd\u017ei\u0173 ir neper\u0161aunam\u0173 liemeni\u0173 dalyse, taip pat chemijos pramon\u0117je, kai reikia atskirti korozij\u0105 sukelian\u010dius garus nuo ne\u0161an\u010di\u0173j\u0173 duj\u0173 arba kondensuoti r\u016bg\u0161\u010di\u0173 tirpalus. Silicio karbido milteliai taip pat naudojami metalurgijoje, ugniai atspariose srityse ir gaminant silicio karbido plok\u0161teles - puslaidininkini\u0173 prietais\u0173 \u017ealiav\u0105.<\/p>\n
Silicio karbidas naudojamas kaip pjovimo med\u017eiaga \u012fvairiuose apdirbimo procesuose. D\u0117l savo kietumo, stiprumo ir ma\u017eos trinties savybi\u0173 silicio karbidas yra puikus pasirinkimas pjovimui vandens srove ir \u0161lifavimui, taip pat juod\u0173j\u0173 med\u017eiag\u0173 ir keramikos poliravimo paslaugoms.<\/p>\n
Silicio karbido gaminiai (moisanito brangakmeniai) pirm\u0105 kart\u0105 komerciniais tikslais prad\u0117ti gaminti apie 1907 m. Silicio karbid\u0105 galima elektroniniu b\u016bdu valdyti elektros srove, elektromagnetiniais laukais ar net \u0161viesos bangomis ir taip moduliuoti jo laidum\u0105; tai leid\u017eia prietaisams veikti auk\u0161tesn\u0117je temperat\u016broje ir esant auk\u0161tesnei \u012ftampai, nesuma\u017einant patikimumo.<\/p>\n
Silicio karbidas turi b\u016bti gaminamas pagal konkre\u010dias eksploatacines specifikacijas, kad b\u016bt\u0173 naudingas tam tikroje srityje, o tam reikia speciali\u0173 \u017eini\u0173, kurias teikia \"Aptiv\", kad b\u016bt\u0173 u\u017etikrinta, jog pasirinktas med\u017eiagos variantas atitikt\u0173 numatyt\u0105 paskirt\u012f.<\/p>","protected":false},"excerpt":{"rendered":"
