Calcium hydride (CaH2) ufa ndi mankhwala omwe adapeza chidwi chifukwa cha kuthekera kwake monga hydrogen yosungirako zinthu. Pokhala ndi chidwi chochulukirachulukira pamagwero amagetsi ongowonjezedwanso komanso kufunikira kosunga mphamvu moyenera, ofufuza akhala akufufuza zida zosiyanasiyana kuti athe kusunga ndikutulutsa mpweya wa haidrojeni. Calcium hydride yatuluka ngati munthu wodalirika chifukwa cha kuchuluka kwake kosungirako haidrojeni komanso mawonekedwe abwino a thermodynamic.
Ubwino umodzi wofunikira wa calcium hydride monga chosungira cha hydrogen ndi mphamvu yake yayikulu ya gravimetric haidrojeni, yomwe imatanthawuza kuchuluka kwa haidrojeni yomwe imatha kusungidwa pagawo lililonse lazinthuzo. Calcium hydride ili ndi theoretical hydrogen yosungirako mphamvu ya 7.6 wt%, kupangitsa kuti ikhale imodzi mwapamwamba kwambiri pakati pa zosungirako zolimba za hydrogen. Izi zikutanthauza kuti mchere wochepa wa calcium hydride ufa ukhoza kusunga kuchuluka kwa haidrojeni, ndikupangitsa kuti ikhale njira yosungiramo komanso yosungira bwino.
Kuphatikiza apo, calcium hydride imawonetsa zinthu zabwino za thermodynamic, zomwe zimalola kusungidwa kosinthika ndikutulutsa mpweya wa haidrojeni. Ikafika ku haidrojeni, calcium hydride imalowa m'thupi kuti ipange calcium hydride hydride (CaH3), yomwe imatha kutulutsa haidrojeni ikatenthedwa. Kukwanitsa kusunga ndi kumasula haidrojeni kumapangitsa kuti calcium hydride ikhale yothandiza komanso yosunthika posungira ma haidrojeni.
Kuphatikiza pa kusungirako kwakukulu kwa haidrojeni komanso katundu wabwino wa thermodynamic, calcium hydride imakhalanso yochuluka komanso yotsika mtengo poyerekeza ndi zinthu zina zosungiramo haidrojeni. Izi zimapangitsa kukhala njira yowoneka bwino pamakina akuluakulu osungira ma haidrojeni, makamaka pankhani yamagetsi ongowonjezedwanso ndi matekinoloje amagetsi amafuta.
Ngakhale kuti calcium hydride imawonetsa lonjezo lalikulu ngati chinthu chosungiramo haidrojeni, pali zovuta zomwe ziyenera kuthetsedwa, monga kukonza mayamwidwe a hydrogen ndi kusungunuka, komanso kukulitsa kukhazikika kwa zinthuzo komanso kulimba kwake. Komabe, kufufuza kosalekeza ndi ntchito zachitukuko zikuyang'ana kwambiri kuthana ndi zovutazi ndikutsegula mphamvu zonse za calcium hydride monga chinthu chothandiza komanso chogwira ntchito chosungiramo haidrojeni.
Pomaliza, ufa wa calcium hydride (CaH2) umakhala ndi kuthekera kwakukulu ngati chinthu chosungiramo haidrojeni, wopatsa mphamvu yosungiramo ma hydrogen, zinthu zabwino za thermodynamic, komanso zotsika mtengo. Pamene kafukufukuyu akupitilira patsogolo, calcium hydride ikhoza kutenga gawo lofunikira pakupangitsa kuti hydrogen ikhale yonyamulira mphamvu zoyera komanso zokhazikika.
