Aluminum carbide

Aluminum carbide ne binary inorganic carbon da aluminum fili. Its sinadaran dabara a matsayin write Al4C3, shi ya dubi matsayin kodadde rawaya ko ruwan kasa crystal da ciwon wani hadadden tsarin layin wutar. Yana iya yin tsayayya da wani Yunƙurin a yawan zafin jiki zuwa 1400 ° C a wata yawa daga 2,36 g / cm³. Kamar yadda wani ɓangare na da raga na carbon atoms ne ba kamar yadda mai hankali carbon anions. Wannan fili an shirya ta kai tsaye dauki na carbon da aluminum a cikin baka makera, shi ne kuma a qananan adadin impurities ba a cikin alli carbide fasaha asalin.

Carbide aluminum: Halayen da kuma Aikace-aikacen

Electrolytic aluminum samar da ya shafi kadaici na fili a matsayin lalata samfur a graphite wayoyin. A cikin akwati inda aluminum carbide aka mayar da martani tare da ruwa ko tsarma acid, methane da aka kafa. Bugu da ƙari, cikin fili reacts tare da oxygen da kuma hydrogen, kuma a cikin akwati na dauki da ruwa da kuma mayar da hankali da sodium hydroxide kafa hadaddun gishiri, da ake kira tetragidroksoalyuminatom methane da sodium. Babu shakka, da fili yana takamaiman jiki Properties, shi yana nufin da Refractive fihirisa alaka da sodium D-line, kuma ya kai 20 ° C. A lokaci guda la'akari da misali Gibbs makamashi da kuma misali entropy samuwar, da Manuniya 196 da kuma isa 88,95Dzh / mol / K. Shiri na wannan fili shi ne zai yiwu a matsayin maras so samfurin a cikin hadaddun sunadarai halayen.

A musamman, karfe matrix composites bisa aluminum matrix da kuma karfafa tare da karfe carbides kamar boron carbide da silicon carbide, na iya taimakawa wajen da aluminum carbide matsayin makaruhai kashi. Irin wannan halin da ake ciki shi ne zai yiwu a yanayin saukan carbon fiber, wanda, a lokacin da ya shiga dauki tare da aluminum matrix a yanayin zafi wucewa 500 ° C, kuma samar da haƙiƙa fili. A lokacin da nassi da sinadaran dauki tsakanin aluminum da kuma jefa silicon carbide Layer iya zama carbide na aluminum, zai rufe silicon carbide barbashi da kuma rage abu ƙarfi.

Duk da haka, wannan sakamako za a iya rage by shafi da silicon oxide barbashi dace ko preoxidation domin kafa silica shafi. Don gane nawa da ruwa ya ƙunshi tritium, da fili ne hõre hydrolysis, sakamakon da aluminum carbide methane. A wannan yanayin, da fili da ake amfani da sinadaran reagent a dauki tare da fili dakatar da ruwa ba tritium da methane. Aluminum carbide, tarwatsa a kan aluminum matrix, taimaka wajen tsare da yawa daga cikin kayan, musamman idan aka hada tare da barbashi silicon carbide.

Hadedde kayan da aluminum carbide za a iya samu ta hanyar inji gami dangane da aluminum foda da graphite barbashi. Tare da wannan fili da ake amfani da matsayin abrasive zuwa high-gudun sabon kayan aikin, ba su da wani taurin tofaz. Wani filin na aikace-aikace ne na fili pyrotechnics, a nan shi damar zuwa samu sakamakon wani firefly, wanda results a wuce kima da ya faru na tartsatsi. Ka lura da cewa a daban-daban sau a pyrotechnics, da ya kullum aka yi amfani da sãɓãwar launukansa a tsanani. A general, wannan fili sami fadi da aikace-aikace a cikin sinadaran masana'antu da kuma samar da filin. Wannan shi ne saboda da sinadaran halaye na aluminum carbide, samar da musamman Properties wanda ba halayyar sauran iri mahadi carbide kungiyar.
