Calcium hydride (CaH2) ntụ ntụ bụ ngwakọta kemịkalụ nke nwetara nlebara anya maka ikike ya dị ka ihe nchekwa hydrogen.Site na nlebara anya na-abawanye na isi mmalite ume ọhụrụ na mkpa maka nchekwa ike dị mma, ndị nchọpụta na-enyocha ihe dị iche iche maka ikike ha ịchekwa na ịhapụ hydrogen gas.Calcium hydride apụtala dị ka onye na-ekwe nkwa n'ihi ikike nchekwa hydrogen dị elu yana njirimara thermodynamic dị mma.
Otu n'ime uru dị mkpa nke calcium hydride dị ka ihe nchekwa hydrogen bụ nnukwu ike hydrogen gravimetric, nke na-ezo aka na ọnụọgụ hydrogen nke nwere ike ịchekwa kwa nkeji nke ihe ahụ.Calcium hydride nwere ikike nchekwa hydrogen nke 7.6 wt%, na-eme ka ọ bụrụ otu n'ime ihe nchekwa hydrogen siri ike.Nke a pụtara na obere obere calcium hydride ntụ ntụ nwere ike ịchekwa nnukwu hydrogen, na-eme ka ọ bụrụ nhọrọ nchekwa nchekwa na nke ọma.
Ọzọkwa, calcium hydride na-egosipụta njirimara thermodynamic dị mma, na-enye ohere maka nchekwa na ntọhapụ nke hydrogen gas.Mgbe ekpughere ya na hydrogen, calcium hydride na-enweta mmeghachi omume kemịkalụ iji mepụta calcium hydride hydride (CaH3), nke nwere ike hapụ hydrogen n'elu ikpo ọkụ.Ikike a nke ịchekwa na ịtọhapụ hydrogen na-eme ka calcium hydride bụrụ ihe bara uru na ihe dị iche iche maka ngwa nchekwa hydrogen.
Na mgbakwunye na ikike nchekwa hydrogen dị elu yana njirimara thermodynamic mara mma, calcium hydride dịkwa oke ọnụ ma dị ọnụ ahịa ma e jiri ya tụnyere ihe nchekwa hydrogen ndị ọzọ.Nke a na-eme ka ọ bụrụ nhọrọ mara mma maka usoro nchekwa nchekwa hydrogen buru ibu, ọkachasị n'ihe gbasara ume ọhụrụ na teknụzụ mmanụ ọkụ.
Ọ bụ ezie na calcium hydride na-egosi nnukwu nkwa dị ka ihe nchekwa hydrogen, a ka nwere ihe ịma aka ndị dị mkpa ka a na-edozi, dị ka imeziwanye kinetics nke absorption hydrogen na desorption, yana ịkwalite nkwụsi ike na ịdịte aka nke ihe ahụ.Ka o sina dị, nchọpụta na-aga n'ihu na mgbalị mmepe na-elekwasị anya n'imeri ihe ịma aka ndị a na imeghe ike zuru oke nke calcium hydride dị ka ihe nchekwa hydrogen bara uru ma dị irè.
N'ikpeazụ, calcium hydride (CaH2) ntụ ntụ na-ejigide ikike dị ukwuu dị ka ihe nchekwa hydrogen, na-enye ikike nchekwa hydrogen dị elu, njirimara thermodynamic dị mma, na ọnụ ahịa bara uru.Ka nyocha na mpaghara a na-aga n'ihu, calcium hydride nwere ike ịrụ ọrụ dị mkpa n'ịkwado nkuchi hydrogen zuru ebe niile dị ka onye na-ebu ume dị ọcha na nke na-adịgide adịgide.
