Sifofin silicon carbide da aka haɗa da amsawa da kuma manyan amfaninsa? Silicon carbide ana iya kiransa carborundum ko yashi mai hana wuta, wani sinadari ne mara tsari, wanda aka raba zuwa kore silicon carbide da baki silicon carbide biyu. Shin kun san sifofin da manyan amfaninsa na silicon carbide? A yau, za mu gabatar da sifofi da manyan amfaninsa na silicon carbide.
Amfani da sinadarin silicon carbide mai amsawa shine amfani da yashi mai siffar quartz, coke na man fetur (ko coking na kwal), slag na itace (ana buƙatar samar da sinadarin silicon carbide mai kore don ƙara gishirin abinci) da sauran kayan masarufi, ta hanyar narkewar zafin jiki mai zafi ta hanyar dumama wutar lantarki.
Halayen silicon carbide mai narkewar reaction:
1. Tsarin watsa zafi da faɗaɗa zafi na silicon carbide. A matsayin wani nau'in kayan da ke hana ruwa gudu, tubalin da aka yi da carbon yana da kyakkyawan juriya ga girgiza. Wannan galibi yana bayyana ne a cikin ƙarfin watsa zafi (haɓakar canja wurin zafi) da ƙarancin haɗin fadada zafi.
2, ƙarfin lantarki na silicon carbide. Silicon carbide abu ne na semiconductor, ƙarfin lantarkinsa ya bambanta da nau'in da adadin ƙazanta da aka shigar a cikin crystallization, kuma juriyar tana tsakanin 10-2-1012Ω·cm. Daga cikinsu, aluminum, nitrogen da boron suna da babban tasiri akan ƙarfin lantarki na silicon carbide, kuma ƙarfin lantarki na silicon carbide tare da ƙarin aluminum yana ƙaruwa sosai.
3. Juriyar silicon carbide. Juriyar silicon carbide tana canzawa tare da canjin zafin jiki, amma a cikin wani takamaiman kewayon zafin jiki da halayen zafin ƙarfe na juriyar ƙarfe suna juyawa. Alaƙar da ke tsakanin juriya da zafin jiki na silicon carbide ta fi rikitarwa. Juriyar silicon carbide mai narkewa yana ƙaruwa tare da yanayin zafi yana tashi zuwa wani ƙima, kuma juriyar yana raguwa lokacin da zafin jiki ya sake tashi.
Amfani da silicon carbide:
1, kayan da ke jure lalacewa - galibi ana amfani da su don yin ƙafafun yashi, niƙa takarda mai laushi, dutse mai laushi, ƙafafun niƙa, man niƙa da samfuran photovoltaic a cikin ƙwayoyin photovoltaic, ƙwayoyin photovoltaic da abubuwan da ke cikin saman niƙa, niƙa da gogewa.
2, kayan da ke da ƙarfi sosai - ana iya amfani da su azaman kayan deoxidizer na masana'antar ƙarfe da kayan da ke jure tsatsa, don yin abubuwan da aka riga aka ƙera a cikin tanda mai zafi mai zafi, sassa masu gyara, da sauransu.
3, yumbu mai aiki - ba wai kawai zai iya rage yawan murhun ba, har ma da inganta ingancin kayayyakin murhun masana'antu, rage lokacin zagayowar, shine mafi kyawun kayan da ba kai tsaye ba don sintering na yumbu mai glaze, ci gaba da yumbu marasa oxide masu zafi, suna nuna faranti mai sintered.
4, karafa masu wuya - kamfanonin ƙarfe da ƙarfe, filin tattara masana'antar ƙarfe, suna da takamaiman aikace-aikace.
5, wani - ana amfani da shi don yin murfin radiation mai nisa-infrared ko farantin silicon carbide na na'urar busar da radiation mai nisa-infrared.
Silicon carbide saboda santsi na sinadarai na halitta, babban ma'aunin canja wurin zafi, ƙaramin ma'aunin faɗaɗa layi, kyakkyawan juriya ga lalacewa, ban da kayan da ke jure lalacewa, akwai wasu manyan amfani, kamar: tare da sabon tsari zuwa manne foda na silicon carbide a cikin bututun centrifugal ko silinda na jikin silinda, zai iya inganta juriya ga lalacewa da ƙara tsawon rayuwar sabis na sau 1 zuwa 2; Ana amfani da shi don yin kayan da ke jure zafi mai yawa, juriya ga girgiza mai zafi, ƙaramin girma, nauyi mai sauƙi da ƙarfi mai yawa, kariyar muhalli da tasirin adana kuzari a bayyane yake. Carbide mai ƙarancin daraja na silicon (wanda ke ɗauke da kusan kashi 85% na SiC) kyakkyawan wakili ne na deoxidizing, wanda za'a iya amfani da shi don hanzarta yawan yin ƙarfe, kuma yana da amfani wajen sarrafa abun da ke ciki da inganta ingancin ƙarfe. Bugu da ƙari, ana amfani da silicon carbide don yin kayan dumama lantarki da yawa na silicon molybdenum sanda.
