Calcium hydride (CaH2) budada waa iskudar kiimiko ah oo helay dareenka awooddeeda sida walxaha kaydinta hydrogen. Iyadoo diiradda la saarayo ilaha tamarta la cusboonaysiin karo iyo baahida loo qabo kaydinta tamarta hufan, cilmi-baarayaashu waxay sahamiyeen qalab kala duwan oo awood u leh inay kaydiyaan oo ay sii daayaan gaasta hydrogen. Calcium hydride wuxuu u soo baxay musharax rajo leh sababtoo ah awoodda kaydinta hydrogen ee sarreeya iyo sifooyinka ku habboon ee kuleyliyaha.
Mid ka mid ah faa'iidooyinka muhiimka ah ee calcium hydride sida walxaha kaydinta hydrogen waa awoodda sare ee hydrogen gravimetric, taas oo loola jeedo qadarka hydrogen ee lagu kaydin karo halbeeg kasta oo walxaha ah. Kaalshiyam hydride waxa uu leeyahay awoodda kaydinta haydaroojin aragti ah 7.6 wt%, taas oo ka dhigaysa mid ka mid ah kuwa ugu sarreeya qalabka kaydinta haydaroojin-state-adag. Tani waxay ka dhigan tahay in qadar yar oo ah kalsiyum hydride budada ah ay ku kaydin karto qadar aad u badan oo hydrogen ah, taas oo ka dhigaysa mid kooban oo wax ku ool ah kaydinta.
Intaa waxaa dheer, kalsiyum hydride waxay soo bandhigaysaa sifooyin heerkulbeegyo wanaagsan, taas oo u oggolaanaysa kaydinta dib-u-noqoshada iyo sii-deynta gaasta hydrogen. Marka ay gaadho hydrogen, kalsiyum hydride waxa uu maraa falcelin kiimikaad si uu u sameeyo calcium hydride hydride (CaH3), kaas oo markaa sii dayn kara hydrogen marka uu kululeeyo. Awooddan si dib loogu kaydiyo oo loo sii daayo hydrogen waxay ka dhigaysaa kalsiyum hydride wax la taaban karo oo la taaban karo oo loogu talagalay codsiyada kaydinta hydrogen.
Marka lagu daro awoodeeda kaydinta haydaroojiin sare iyo sifada heerkulbeegyada wanaagsan, kalsiyum hydride sidoo kale waa mid aad u badan oo kharash-ool ah marka la barbar dhigo agabka kaydinta hydrogen ee kale. Tani waxay ka dhigaysaa mid soo jiidasho leh nidaamyada kaydinta hydrogen ee baaxadda leh, gaar ahaan marka la eego macnaha tamarta la cusboonaysiin karo iyo tignoolajiyada unugyada shidaalka.
Iyadoo kalsiyum hydride ay muujinayso ballanqaad weyn oo ah sheyga kaydinta hydrogen, weli waxaa jira caqabado u baahan in wax laga qabto, sida hagaajinta kinetics nuugista hydrogen iyo nadiifinta, iyo sidoo kale kor u qaadida xasiloonida walxaha. Si kastaba ha ahaatee, dadaallada cilmi-baarista ee socda iyo horumarinta ayaa diiradda saaraya sidii looga gudbi lahaa caqabadahan iyo in la furo awoodda buuxda ee calcium hydride sida wax ku ool ah oo wax ku ool ah kaydinta hydrogen.
Gebagebadii, budada calcium hydride (CaH2) waxa ay haysaa awood weyn oo ah shay kaydinta hydrogen, oo bixisa awoodda kaydinta hydrogen sare, sifooyinka heerkulbeegga ee wanaagsan, iyo waxtarka qiimaha. Maaddaama cilmi-baarista goobtan ay sii socoto, kalsiyum hydride ayaa laga yaabaa inay door muhiim ah ka ciyaarto awood u qaadashada baahsanaanta ee hydrogen sida side tamar nadiif ah oo waara.
