Aluminum carbide

Aluminum carbide bụ a ọnụọgụ abụọ inorganic carbon na aluminum compound. Ya chemical usoro dị ka akwụkwọ, Al4C3, ya anya dị ka a acha odo ma ọ bụ aja aja crystal enwe a mgbagwoju bughi okporo. Ọ bụ ike idi a ịrị elu okpomọkụ ka 1400 ° C na a njupụta nke 2,36 g / cm³. Dị ka akụkụ nke ya lattice nke carbon atọm bụ ugbu dị ka pụrụ iche carbon anions. Nke a compound na-akwadebe site kpọmkwem mmeghachi omume nke carbon na aluminum na aak ọkụ, ọ bụ na-a obere ego nke adịghị ugbu ke calcium carbide technical malite.

Carbide aluminum: Njirimara na Ngwa

Electrolytic aluminum mmepụta-agụnye iche nke compound ka a corrosion ngwaahịa na graphite electrodes. N'ihe banyere ebe aluminum carbide na-meghachi omume na mmiri ma ọ bụ itughari acid, methane a kpụrụ. Ọzọkwa, compound mkpatụ na oxygen na hydrogen, na na ikpe nke na mmeghachi omume na mmiri na-etinye uche na sodium hydroxide kpụrụ mgbagwoju nnu, na-akpọ tetragidroksoalyuminatom methane na sodium. Kwesịrị ịdị, ndị compound nwere kpọmkwem ahụ Njirimara, ọ na-ezo aka na Refractive indices metụtara sodium D-akara, na esịmde 20 Celsius C. N'otu oge ahụ na-echebara ọkọlọtọ Gibbs ike na ọkọlọtọ entropy nke guzobere, na-egosi 196 na iru 88,95Dzh / mol / K. Nkwadebe nke a compound bụ omume dị ka achọghị ngwaahịa na mgbagwoju chemical Jeremaya mere.

Karịsịa, metal matriks composites dabeere na aluminum matriks na mesikwuru na metal carbides dị ka boron carbide na sịlịkọn carbide, nwere ike na-eme ka aluminum carbide dị ka ihe ekwesighi mmewere. Ọnọdụ dị otú ahụ bụ na o kwere omume na ikpe nke carbon eriri, nke, mgbe ịbanye mmeghachi omume na aluminum matriks na okpomọkụ uku 500 ° C, na-enyekwa ebumnobi compound. N'oge Itie nke chemical mmeghachi omume n'etiti aluminum tubà sịlịkọn carbide oyi akwa nwere ike a carbide nke níle Önwa, ọ ga-ekpuchi sịlịkọn carbide urughuru ma belata ihe ike.

Otú ọ dị, nke a pụrụ isi kwuo ya nwere ike belata mkpuchi na sịlịkọn oxide ahụ kwesịrị ekwesị ma ọ bụ preoxidation maka akpụ silica mkpuchi. Iji mata otú ihe mmiri nwere tritium, onyinye na-doro hydrolysis, n'ihi na aluminum carbide methane. Na nke a, na compound na-eji dị ka chemical reagent na mmeghachi omume na compound kwụsịtụrụ na mmiri na-enye tritium na methane. Aluminum carbide, chụgara na aluminum matriks, na-enyere iji chebe njupụta nke ihe onwunwe, karịsịa ma ọ bụrụ na ọ na-achọkwa na onye ahụ nke sịlịkọn carbide.

Mejupụtara ihe nke aluminum carbide nwere ike inweta site n'ibu alloys dabeere na aluminum ntụ ntụ na graphite ahụ. Yana a compound na-eji dị ka ihe abrasive ka elu-ọsọ ọnwụ ngwaọrụ, na-enye ha a ekweghị ekwe nke topaz. Ọzọ ubi nke ngwa bụ compound nke pyrotechnics, ebe a na-enye ohere iji nweta mmetụta nke a firefly, nke utịp ke oké omume nke ikerike. Rịba ama na n'oge dị iche iche na pyrotechnics, ọ ka mgbe e ji ya mee mgbanwe osisi ike. Ke ofụri ofụri, a compound okụt obosara ngwa ke chemical ụlọ ọrụ na mmepụta ubi. Nke a bụ n'ihi na chemical e ji mara nke aluminum carbide, na-enye ya pụrụ iche Njirimara nke ndị e ji mara nke ọzọ iche nke ogige carbide otu.
