I-calcium hydride (CaH2) ipowder yikhemikhali yekhemikhali eye yafumana ingqalelo kwikhono layo njengento yokugcina i-hydrogen. Ngokugxila okukhulayo kwimithombo yamandla avuselelekayo kunye nesidingo sokugcinwa kwamandla ngokufanelekileyo, abaphandi baye baphonononga izinto ezahlukeneyo zokukwazi ukugcina kunye nokukhulula igesi ye-hydrogen. I-calcium hydride iye yavela njengomgqatswa othembisayo ngenxa yomthamo wayo ophezulu wokugcinwa kwe-hydrogen kunye neempawu ezifanelekileyo ze-thermodynamic.
Enye yeenzuzo eziphambili ze-calcium hydride njengento yokugcina i-hydrogen yi-high gravimetric hydrogen capacity, ebhekisela kubungakanani be-hydrogen obunokugcinwa ngeyunithi yobunzima bezinto eziphathekayo. I-Calcium hydride inomthamo wogcino we-hydrogen wethiyori we-7.6 wt%, iyenza ibe yenye yezona zinto ziphezulu phakathi kwezinto zokugcina i-hydrogen. Oku kuthetha ukuba umlinganiselo omncinci we-calcium hydride powder unokugcina inani elikhulu le-hydrogen, okwenza kube yinto edibeneyo kunye neyokugcina yokugcina.
Ngaphaya koko, i-calcium hydride ibonisa iipropathi ezifanelekileyo ze-thermodynamic, ezivumela ukugcinwa okubuyela umva kunye nokukhululwa kwegesi ye-hydrogen. Xa ibonakaliswe kwi-hydrogen, i-calcium hydride ifumana ukusabela kweekhemikhali ukwenza i-calcium hydride hydride (CaH3), enokuthi emva koko ikhulule i-hydrogen xa ifudumala. Obu buchule bokugcina ngokubuyisela umva kunye nokukhulula i-hydrogen yenza i-calcium hydride ibe yimathiriyeli esebenzayo neguquguqukayo kwizicelo zokugcina i-hydrogen.
Ukongeza kumthamo wayo ophezulu we-hydrogen kunye neempawu ezifanelekileyo ze-thermodynamic, i-calcium hydride nayo ininzi kwaye inexabiso eliphantsi xa kuthelekiswa nezinye izinto zokugcina i-hydrogen. Oku kuyenza ibe lukhetho olunomtsalane kwiinkqubo ezinkulu zokugcina i-hydrogen, ngakumbi kumxholo wamandla avuselelekayo kunye nobuchwepheshe beeseli zamafutha.
Nangona i-calcium hydride ibonisa isithembiso esikhulu njengento yokugcina i-hydrogen, kusekho imingeni efuna ukulungiswa, njengokuphucula i-kinetics ye-hydrogen absorption kunye ne-desorption, kunye nokuphucula ukuzinza kunye nokuqina kwezinto. Nangona kunjalo, uphando oluqhubekayo kunye neenzame zophuhliso zijolise ekoyiseni le mingeni kunye nokuvula amandla apheleleyo e-calcium hydride njengento esebenzayo kunye nesebenzayo yokugcina i-hydrogen.
Ukuqukumbela, i-calcium hydride (CaH2) ipowder ibambe amandla amakhulu njengesixhobo sokugcina i-hydrogen, inikezela ngomthamo omkhulu wokugcina i-hydrogen, iipropathi ezifanelekileyo ze-thermodynamic, kunye neendleko ezifanelekileyo. Njengoko uphando kule ntsimi luqhubela phambili, i-calcium hydride inokudlala indima ebalulekileyo ekwenzeni ukwamkelwa ngokubanzi kwe-hydrogen njengento ehambisa amandla ecocekileyo kunye nezinzileyo.
