Aruminiyamu carbide

Aluminum carbide chinhu binary inorganic kabhoni pamwe aruminiyamu akakura. Its makemikari payakavakirwa sezvo nyora Al4C3, zvinoita somunhu rakachenuruka yero kana shava sekristaro ane kunzwisisa STRUCTURAL afoot. Hazvina kumira kuwedzera tembiricha kuti 1400 ° C ari arambe achirema pamusoro 2.36 g / cm³. Sechikamu ayo rekamuri reimba kabhoni maatomu varipo sezvo discrete kabhoni anions. remubatanidzwa Izvi wakagadzirwa rakananga maitiro kabhoni pamwe aruminiyamu ari riemukaari chamatare, asiwo zviduku uwandu nouipi vaivapo muna karusiyamu carbide rwokugadzira mavambo.

Carbide aruminiyamu: Characteristics uye Application

Electrolytic aruminiyamu kugadzirwa kunosanganisira voga pakati mukomboni sechinhu ngura chigadzirwa mu graphite electrodes. In Kana apo aruminiyamu carbide iri vakaita nemvura kana sanganisa acid, methane aumbwa. Uyezve, mukomboni ikasakendenga nemhepo sehydrogen, uye nyaya maitiro nemvura uye pfungwa yacho yavaibvisa hydroxide kuumbwa kunzwisisa munyu, akadana tetragidroksoalyuminatom methane uye yavaibvisa. Sezvingatarisirwa, mukomboni ane chaizvo zvinooneka ehupfumi, rinoreva kuti refractive indices chokuita yavaibvisa D-mutsetse, uye kunosvika 20 ° C. Panguva iyoyowo kufunga mureza Gibbs simba uye mwero entropy pamusoro inotungamirwa, iyo zviratidzi 196 uye kusvika 88,95Dzh / mol / K. Kugadzirira remubatanidzwa zvinokwanisika sezvo chigadzirwa pasingadiwi mune kunzwisisa nemakemikari.

Zvikurukuru, chinoumbwa simbi chizvaro kwakavakirwa aruminiyamu chizvaro uye kusimba pamwe simbi carbides akadai Boron carbide nesilicon carbide, kungawedzera aruminiyamu carbide sechinhu kunaka maatomu akafanana. ezvinhu kwakadaro kunobvira panyaya kabhoni faibha, iyo, kana achipinda maitiro pamwe aruminiyamu chizvaro pa tembiricha kwazvo 500 ° C, rinopawo chinangwa akakura. Munguva ndima yacho kwemakemikari maitiro pakati aruminiyamu uye vakakanda nesilicon carbide rukoko angava carbide pakati aruminiyamu, zvichava kufukidza nesilicon carbide PARTICIPLE uye kuderedza zvinhu simba.

Zvisinei, izvi kunogona kuderedzwa yokunamisa nesilicon oxide nezvimedu akakodzera kana preoxidation yokuva silica unhani. Kuziva zvakadini mvura ine tritium, mukomboni iri pasi hydrolysis, zvichiguma aruminiyamu carbide methane. Panyaya iyi, mukomboni inoshandiswa sezvo kwemakemikari reagent ari maitiro pamwe mukomboni yakaturikwa nemvura anopa tritium uye methane. Aluminum carbide, vakapararira pamusoro aruminiyamu chizvaro, kunobatsira kuchengetedza arambe achirema kwemashoko, kunyanya kana zvasangana tudonhwe nesilicon carbide.

Chinoumbwa zvinhu zviri aruminiyamu carbide kunogona kuwanikwa kuburikidza zvemaziso alloys kwakavakirwa aruminiyamu upfu uye graphite inoramba. Pamwe remubatanidzwa ichi rinoshandiswa sechinhu hasha kune mukuru-nokukurumidza nokuveza maturusi, achivapa neukukutu topasi. Chimwe munda chikumbiro ndiyo mukomboni pamusoro pyrotechnics, pano zvinoita kuti vawane zvinoita Chinotonhora, chinoguma kunyanya panowanikwa nezvitsiga. Cherechedza kuti panguva dzakasiyana mune pyrotechnics agara rakashandiswa pamwe siyana zvikuru. Kazhinji, remubatanidzwa ichi anowana paupamhi kushanda muna zvemakemikari indasitiri uye kugadzirwa munda. Izvi imhaka makemikari zvechadenga aruminiyamu carbide, ichipa ehupfumi ayo akasiyana dzisiri yo dzimwe mhando boka yeimwe carbide.
