Carbide aluminium

carbide Aluminum waa carbon ah binary imanba leh xarunta aluminium. Its formula kiimikada sida Al4C3 qortaan, waxa ay u muuqataa sidii madarad oo cirro leh huruud ah ama maariin ah isagoo ah Roobka dhismaha adag. Waa in ay u adkeysan u kaca ah ee heerkulka si 1400 ° C at cufnaanta ah 2,36 g / cm³ awoodaan. Iyadoo qeyb ka ah daaqaddii of atamka carbon joogaan sidii anions carbon Discrete. Xarunta Tani waxaa loo diyaariyey by falcelin toos ah carbon la aluminium foorno lagu bedello, sidoo kale waa qadar yar ee nijaasta jooga dalka calcium carbide asal farsamo.

Carbide aluminium: Calaamadaha iyo Codsiga

wax soo saarka aluminium Electrolytic ku lug go'doomin ee xarunta sida wax soo saarka daxalka in electrodes graphite ah. In kiiska halkaas oo carbide aluminium waa jawaabay biyo ama milo acid, methane waxaa la aasaasay. Intaas waxaa sii dheer, xarunta sameynayso la oxygen iyo hydrogen, iyo in ay dhacdo fal-celin iyo biyo, iyo xoogga hydroxide sodium sameeyay cusbo qalafsan, loo yaqaan tetragidroksoalyuminatom methane iyo sodium. Dabcan, xarunta leeyahay sifooyin jirka gaar ah, waxaa loola jeedaa in ay ku indices Refractive la xiriira sodium D-line, oo gaadho 20 ° C. Isla mar ahaantaana ay tixgeliyaan caadiga tamarta Gibbs iyo entropy caadiga ah ee formation, tilmaamayaasha ah 196 oo gaari 88,95Dzh / mol / K. Diyaarinta xarunta tani waa suurto gal ah sida alaabta aan la rabin in falgalka kiimikada adag.

Gaar ahaan, darka furta biraha ku salaysan shaxda aluminium iyo xoojinay mid carbides biraha sida carbide boron iyo carbide Silicon, waxaa laga yaabaa in ay gacan ka carbide aluminium sida element ah aan loo baahnayn. xaaladda noocan oo kale ah waxaa suurto gal ah in ay dhacdo fiber carbon, kaas oo, marka laga galo dareen-celin la furta aluminium marka heerkulku aad iyo aad 500 ° C, sidoo kale waxay bixisaa xarunta Ujeedada. Inta lagu guda jiro marinka ee reaction kiimikada dhexeeya aluminium iyo tuuri Silicon lakabka carbide laga yaabaa carbide ah aluminium, waxaa dabooli doonaa walxaha Silicon carbide iyo in la yareeyo wax xoog.

Si kastaba ha ahaatee, saamaynta this waa la dhimi karaa by daahan Qurub xabagta Silicon ku haboon ama preoxidation waayo sameynta daahan silica. Si loo garto inta uu leeg biyaha ku jira tritium, xarunta waxaa la hoos geliyey hydrolysis, taasoo keentay in methane carbide aluminium. Xaaladdan oo kale, xarunta waxaa loo isticmaalaa sida reagent kiimikada falcelinta la xarunta ganaax biyo siinayaa tritium iyo methane. carbide Aluminum, kala firdhiyey on furta aluminium, waxay ka caawisaa si loo ilaalin lahaa cufnaanta mid ah waxyaabaha la, gaar ahaan haddii ay weheliso qayb ka mid ah carbide Silicon.

qalabka darka of carbide aluminium waxaa laga heli karaa iyada oo loo marayo Alloys farsamo ku salaysan budada aluminium iyo qayb ka graphite. Oo ay la socdaan xarunta this waxaa loo isticmaalaa sida hadal haynta ah in qalab goynta-xawaaraha sare, wuxuuna iyaga siiyey qalbi engegnaantooda ah iyo tobasiyos. beer kale codsiga waa xarunta of pyrotechnics, halkan waxay u saamaxdaa in la helo saamaynta firefly ah, taas oo keenta in dhacdo-dhaafka ah ee dhimbiiluhu. Ogsoonow in waqtiyo kala duwan ee pyrotechnics, waxa uu had iyo jeer lagu isticmaalo adag ee kala duwan. Guud ahaan, xarunta this helaa codsi ballaaran in industry kiimikada oo beerta soo saarka. Tan waxa u sabab ah sifooyinka kiimikada ee carbide aluminium, bixinta hantida gaarka ah oo aan caan ku noocyada kale ee group xeryahooda carbide.
