Calcium Hydride (CAS: 7789-78-8) ndi alkaline earth metal hydride, ngakhale kuti siikhazikika kuposa lithiamu hydride, koma yokhazikika kuposa borohydride ena alkali zitsulo.Chemical formula ndi CaH2.Kulemera kwa mamolekyu ndi 42.10.Akakumana ndi mpweya wonyowa wa haidrojeni amatuluka, ndipo calcium hydroxide imachoka.Chigawo cha 1.9.Kutentha kwa kutentha ndi pafupifupi 600 ℃.Malo osungunuka ndi 816 ℃ (hydrogen).Mukakumana ndi madzi, ma carboxylic acid, ma alcohols otsika, amatha kuwola kuti apange haidrojeni.Kuwola Kukafika 600 ℃, kumayamba kuwola.Pa kutentha kwa chipinda, sichingathe kuchitapo kanthu ndi mpweya wouma, nayitrogeni, chlorine, koma imatha kuchitapo kanthu pa kutentha kwakukulu.Izi zitha kupanga CaO, Ca3N2, CaCl2, motsatana.Pa kutentha kwa firiji, imatha kuchitapo kanthu ndi madzi ndipo mankhwalawa ndi calcium hydroxide ndi hydrogen.Itha kugwiritsidwa ntchito ngati chochepetsera komanso chowongolera mu organic synthesis, ndi desiccant popanga zinthu za haidrojeni.amagwiritsidwa ntchito nthawi zonse m'ma laboratories kupanga tinthu tating'ono ta haidrojeni yoyera kwambiri poyesera.Amagwiritsidwa ntchito ngati powdery metallurgy.Zochepetsera, chowumitsira gasi ndi ma reagents osanthula mankhwala.Organic kaphatikizidwe.Calcium hydride imagwiritsidwa ntchito ngati chowumitsa bwino chosungunulira ma aprotic base-stable monga ethers ndi tertiary amines.Ndiwothandiza kuchepetsa madzi m'thupi mu kaphatikizidwe ka aldehyde enamines muzokolola zambiri komanso chiyero.
Gulu: Zinthu zophulika.
Makhalidwe owopsa owopsa: Pamene zomwe zimatenthedwa ndi tetrahydrofuran, zimatha kuyambitsa kuphulika;mukasakaniza ndi potaziyamu chlorate, hypochlorite, bromate, perchlorate, imamva kutentha, imakhudzidwa ndi mikangano komanso yophulika.
Kusungirako Makhalidwe: Treasury amafuna mpweya wochepa kutentha kuyanika;shockproof, chinyezi, motsutsana ndi kutentha kwakukulu.
Chozimitsa: thovu, mpweya woipa, ufa wowuma.
