Gabatar da samfurin da amfani da baƙin silicon carbide
Baƙar silikon carbide(wanda aka rage masa suna da baƙin silicon carbide) wani abu ne na wucin gadi wanda ba na ƙarfe ba wanda aka yi da yashi mai siffar quartz da kuma man fetur coke a matsayin babban kayan albarkatun ƙasa kuma ana narkar da shi a zafin jiki mai yawa a cikin tanderu mai juriya. Yana da kamannin baƙi-toka ko baƙi mai duhu, mai matuƙar tauri, kyakkyawan yanayin zafi da kwanciyar hankali na sinadarai. Kayan aiki ne mai kyau na masana'antu kuma ana amfani da shi sosai a fannin goge-goge, kayan da ba su da ƙarfi, ƙarfe, yumbu, kayan lantarki da sauran fannoni.
Ⅰ. Halayen aiki na baƙin silicon carbide
Taurin Mohs nabaƙin silicon carbideYana da tsayi har zuwa 9.2, na biyu bayan lu'u-lu'u da nitride mai siffar sukari, kuma yana da juriya mai ƙarfi da juriyar lalacewa. Wurin narkewar sa yana da kusan 2700°C, kuma yana iya kiyaye kwanciyar hankali a cikin yanayin zafi mai zafi kuma ba shi da sauƙin ruɓewa ko ruɓewa. Bugu da ƙari, yana da kyakkyawan juriyar zafi da ƙarancin ƙimar faɗaɗa zafi, kuma har yanzu yana nuna kyakkyawan kwanciyar hankali na girgizar zafi a ƙarƙashin yanayin zafi mai yawa da matsin lamba mai yawa.
Dangane da halayen sinadarai, baƙar silikon carbide yana da kyakkyawan juriya ga lalata acid da alkalis, kuma ya dace musamman don amfani da masana'antu a cikin mawuyacin yanayi. Babban ƙarfinsa kuma ya sanya shi madadin kayan dumama wutar lantarki da filayen semiconductor.
Ⅱ. Manyan siffofi da ƙayyadaddun bayanai
Ana iya yin silicon carbide mai launin baƙi zuwa siffofi daban-daban bisa ga girman ƙwayoyin cuta da amfaninsu daban-daban:
Kayan toshewa: manyan lu'ulu'u bayan narkewa, galibi ana amfani da su don sake sarrafawa ko azaman ƙarin ƙarfe;
Yashi mai siffar granular (yashi mai siffar F/yashi mai siffar P): ana amfani da shi wajen yin ƙafafun niƙa, goge gogewar yashi, takarda mai siffar sandpaper, da sauransu.
Ƙaramin foda (jerin W, D): ana amfani da shi don niƙa, gogewa, yin simintin yumbu, da sauransu.
Foda mai matakin Nano: ana amfani da shi don tukwane na lantarki masu inganci, kayan haɗin kai na thermal, da sauransu.
Girman barbashi yana tsakanin F16 zuwa F1200, kuma girman barbashi na ƙananan foda zai iya kaiwa matakin nanometer, wanda za'a iya keɓance shi bisa ga buƙatun fasaha na filayen aikace-aikace daban-daban.
Ⅲ. Manyan wuraren amfani da baƙin silicon carbide
1. Kayan aikin gogewa da niƙa
Abrasives su ne wuraren da aka fi amfani da su a gargajiya kuma aka fi amfani da su a fannin amfani da baƙin silicon carbide. Ta hanyar amfani da ƙarfinsa da kuma ƙarfinsa mai kaifi, ana iya amfani da baƙin silicon carbide don ƙera samfuran goge-goge iri-iri, kamar ƙafafun niƙa, faifan yankewa, takarda mai yashi, kan niƙa, manna niƙa, da sauransu, waɗanda suka dace da niƙa da sarrafa kayan kamar ƙarfe, ƙarfe, ƙarfe marasa ƙarfe, yumbu, gilashi, quartz, da kayayyakin siminti.
Amfaninsa shine saurin niƙawa cikin sauri, ba shi da sauƙin toshewa, da kuma ingantaccen sarrafawa mai yawa. Ana amfani da shi sosai a fannin sarrafa ƙarfe, kera injina, adon gini da sauran masana'antu.
2. Kayan da ke da tsaurin kai
Saboda yawan zafinsa da juriyarsa ga tsatsa, ana amfani da baƙin silicon carbide a fannin kayan da ke hana zafi sosai. Ana iya yin sa a cikin tubalin silicon carbide, rufin tanderu, bututun kariya na thermocouple, kayan aikin murhu, bututun ƙarfe, tubalin tuyere, da sauransu, kuma ana amfani da shi sosai a masana'antu masu zafin gaske kamar ƙarfe, ƙarfe marasa ƙarfe, wutar lantarki, gilashi, siminti, da sauransu, don tsawaita rayuwar kayan aiki da inganta amincin aiki.
Bugu da ƙari, kayan silicon carbide suna da kyawawan kaddarorin antioxidant a cikin yanayin iskar oxygen mai zafi kuma sun dace da amfani a cikin mahimman sassan tanderun zafi, tanderun fashewa da sauran kayan aiki.
3. Masana'antar ƙarfe
A cikin ayyukan ƙarfe kamar yin ƙarfe da siminti, ana iya amfani da baƙin silicon carbide a matsayin mai cire sinadarin oxidizer, mai dumama ruwa da kuma mai sake yin amfani da shi. Saboda yawan sinadarin carbon da ke cikinsa da kuma saurin fitar da zafi, yana iya inganta yadda ake narkewa da kuma inganta ingancin ƙarfe mai narkewa. A lokaci guda kuma, yana iya rage yawan datti a cikin aikin narkewa da kuma taka rawa wajen tsarkake ƙarfe mai narkewa.
Wasu injinan ƙarfe suna ƙara wani kaso na silicon carbide don daidaita abun da ke cikin narkewar ƙarfe da ƙarfe mai ƙarfi don adana farashi da inganta aikin siminti.
4. Yumbura da kayan lantarki
Bakar silikon carbide shima muhimmin abu ne na kayan aiki na yumbu mai aiki. Ana iya amfani da shi don shirya yumbu mai tsari, yumbu mai jure lalacewa, yumbu mai jure zafi, da sauransu, kuma yana da fa'idodi masu yawa a fannoni na lantarki, masana'antar sinadarai, injina, da sauransu. Yana da kyakkyawan juriyar zafi, tare da juriyar zafi har zuwa 120 W/m·K, kuma galibi ana amfani da shi a cikin kayan watsa zafi mai jure zafi, kayan haɗin zafi da abubuwan watsa zafi na LED.
Bugu da ƙari, silicon carbide ya shiga fagen na'urorin lantarki masu amfani da wutar lantarki a hankali kuma ya zama kayan aiki na asali don na'urorin lantarki masu amfani da wutar lantarki mai zafi da ƙarfin lantarki. Duk da cewa tsarkin silicon carbide mai launin baƙi ya ɗan yi ƙasa da na silicon carbide mai launin kore, ana kuma amfani da shi a wasu samfuran lantarki masu matsakaici da ƙarancin wutar lantarki.
5. Masana'antar samar da wutar lantarki ta hasken rana da sabbin makamashi
Ana amfani da foda mai launin baki na silicon carbide sosai wajen yanke wafers na silicon a masana'antar photovoltaic. A matsayin mai gogewa a cikin tsarin yanke waya na lu'u-lu'u, yana da fa'idodin tauri mai ƙarfi, ƙarfi.yankeƙarfi, ƙarancin asara, da kuma santsi na yankewa, wanda ke taimakawa wajen inganta ingancin yankewa da yawan amfanin wafers na silicon da kuma rage yawan asarar wafer da farashin samarwa.
Tare da ci gaba da haɓaka sabbin makamashi da sabbin fasahohin kayan aiki, ana kuma haɓaka silicon carbide don fannoni masu tasowa kamar ƙarin electrode na lithium battery da kuma ɗaukar membrane na yumbu.
Ⅳ. Takaitawa da hangen nesa
Bakar silikon carbide yana taka muhimmiyar rawa a fannoni da dama na masana'antu tare da kyawawan halayensa na injiniya, zafi da sinadarai. Tare da ci gaba da ci gaba da fasahar masana'antu, sarrafa girman barbashi na samfura, tsaftace tsarki da ci gaba da faɗaɗa filayen amfani, bakar silikon carbide yana haɓaka zuwa babban aiki da daidaito.
Nan gaba, tare da karuwar masana'antu kamar sabbin makamashi, yumbu na lantarki, da kuma manyan kayayyakiniƙa da kuma masana'antu masu wayo, baƙar silikon carbide za ta taka muhimmiyar rawa a fannin masana'antu masu inganci kuma ta zama babban ɓangare na tsarin fasahar kayan zamani.
