I-calcium hydride (i-cah2) powder iyindawo yamakhemikhali etholwe amathuba ayo njengezindawo zokugcina i-hydrogen. Ngokugxila okwandayo emithonjeni yamandla evuselelekayo kanye nesidingo sokugcinwa kwamandla okusebenzayo, abacwaningi bebelokhu behlola izinto ezahlukahlukene zekhono labo lokugcina nokukhipha igesi ye-hydrogen. I-calcium hydride ivele njengomuntu othembisayo ngenxa yekhono layo eliphakeme le-hydrogen kanye nezakhiwo ezinhle ze-thermodynamic.
Enye yezinzuzo ezisemqoka ze-calcium hydride njengezinto zokulondolozwa ze-hydrogen zingamandla alo aphezulu we-hydrogen, abhekisele kwinani le-hydrogen elingagcinwa ngeyunithi ngayinye yezinto ezibonakalayo. I-calcium hydride inesilinganiso sokugcina se-hydrogen se-auprogen esingu-7.6 wt%, okwenza kube ngomunye wokugcina phakathi kwezinto zokwakha eziqinile ze-hydrogen. Lokhu kusho ukuthi inani elincane le-calcium hydride powder elingagcina inani elibalulekile le-hydrogen, okwenza kube inketho yokugcina ehlakaniphile nefanele.
Ngaphezu kwalokho, i-calcium hydride imibukiso evumayo ye-thermodynamic. Lapho kuvezwa i-hydrogen, i-calcium hydride ibhekana nokusabela kwamakhemikhali ukuze kukhishwe i-calcium hydride hydride (Cah3), engakhipha i-hydrogen ekushiseni. Leli khono lokugcina kabusha esitolo futhi udedele i-hydrogen yenza i-calcium hydride i-calcium hydride impahla esebenzayo nezinto eziguquguqukayo zezicelo zokugcina i-hydrogen.
Ngokungeziwe kumthamo wayo ophezulu we-hydrogen kanye nezakhiwo ezinhle ze-thermodynamic, i-calcium hydride inokuningi futhi kungabizi kakhulu uma kuqhathaniswa nezinye izinto zokugcina i-hydrogen. Lokhu kwenza kube inketho ekhangayo yezinhlelo ezinkulu zesitoreji se-hydrogen, ikakhulukazi umongo wamandla avuselelekayo namandla okuphehla amaselula.
Ngenkathi i-calcium hydride ikhombisa isithembiso esihle njengezinto zesitoreji se-hydrogen, kunezingqinamba ezidinga ukubhekelwanga, njengokuthuthukisa ama-kinetics wokufakwa kwe-hydrogen kanye nentuthuko, kanye nokwenza ngcono ukuqina kokuqina nokuqina. Noma kunjalo, ucwaningo oluqhubekayo kanye nemizamo yentuthuko igxile ekunqobeni lezi zinselelo futhi ivule amandla aphelele we-calcium hydride njengezinto ezisebenzayo nezisebenzayo zokugcina i-hydrogen.
Ekuphetheni, i-calcium hydride (i-cah2) powder ibamba amandla amakhulu njengezinto ezigciniwe ze-hydrogen, enikeza umthamo wesitoreji esiphezulu we-hydrogen, izakhiwo ezinhle ze-thermodynamic, kanye nokusebenza kwezindleko. Njengoba ucwaningo kule nkambu luyaqhubeka ukuqhubekisela phambili, i-calcium hydride ingahle ibambe iqhaza elibalulekile ekwenzeni amandla okukhuphuka kwe-hydrogen njenge-hydrogen evamile njenge-orgy ye-ezama ohlanzekile futhi esimeme.
