Cacium hydride (chah2) hmoov yog cov tshuaj lom neeg uas tau txais cov xim rau nws lub peev xwm los ua cov khoom siv hydrogen cia. Nrog rau kev pom tseeb ntxiv rau lub zog txuas ntxiv thiab cov kws tshawb nrhiav tau tshawb xyuas ntau yam rau lawv lub peev xwm khaws cia thiab tso cov pa roj. Calcium hydride tau tawm los ua cov neeg muaj kev sib cav sib ceg vim nws cov hydrogen cia muaj peev xwm thiab cov khoom muaj txiaj ntsig thermodynamic zog.
Ib qho ntawm cov ntsiab lus tseem ceeb ntawm calcium hydride ua cov khoom siv hydrogen me yog qhov muaj peev xwm khaws tau ib chav ntawm cov khoom siv. Calcium hydride muaj theoretical hydrogen cia muaj peev xwm ntawm 7.6 wt%, ua rau nws ib qho siab tshaj plaws ntawm cov khoom siv ntawm hydrogen cia. Qhov no txhais tau hais tias qhov tsawg dua ntawm cov hmoov calcium hydride hmoov tuaj yeem khaws cov khoom siv tseem ceeb ntawm hydrogen, ua rau nws xaiv cov khoom lag luam kom zoo.
Tsis tas li ntawd, calthium hydride cov khoom pov puag haum cua zoo, tso cai rau cov khoom lag luam tshiab thiab tso tawm ntawm hydrogen gas. Thaum raug rau hydrogen, calcium hydride undergoes siv calcium hydride hydride (CAH3), uas tuaj yeem tso hydrogen thaum cua sov. Qhov peev xwm no los thim rov qab thiab tso hydrogen ua cov calcium hydride cov khoom siv hydrogen cia thiab ntau yam rau cov ntawv thov hydrogen cia.
Ntxiv nrog rau nws cov hydrogen cia muaj peev xwm thiab cov dej khov kho thermodynamic kuj muaj ntau yam thiab raug nqi rau lwm cov khoom siv hydrogen cia khoom. Qhov no ua rau nws pom zoo rau cov khoom lag luam hydrogen cia loj, tshwj xeeb hauv cov ntsiab lus ntawm lub zog txuas ntxiv thiab roj cell technologies.
Thaum hydride hydride pom cov lus cog tseg zoo heev li hydrogen cia khoom, xws li kev txhim kho cov khoom siv hydrogen, thiab ua kom zoo dua li kev txhim kho cov khoom siv ruaj khov thiab ua kom ruaj khov. Txawm li cas los xij, txuas ntxiv tshawb nrhiav thiab kev nthuav dav rau kev kov yeej cov kev sib tw no thiab muaj peev xwm ua kom muaj txiaj ntsig zoo raws li cov khoom siv hydrogen cia thiab txuag cov khoom siv hydrogen.
Hauv kev xaus, calcium hydride (chah2) hmoov tuav cov khoom siv hydrogen cia, muaj peev xwm hydrogen cia khoom, thiab nqi zog thermodynamic zog, thiab tus nqi-ua hauj lwm zoo. Raws li kev tshawb fawb hauv daim teb no txuas ntxiv ua ntej, calcium hydride yuav ua lub luag haujlwm tseem ceeb hauv kev nce hydrogen ua ib lub zog huv thiab muaj zog.
