Lithium hydride bụ ihe na-acha ọcha na-acha ntụ ntụ, translucent, siri ike ma ọ bụ ntụ ntụ na-enweghị isi nke na-agba ọchịchịrị ngwa ngwa mgbe ikpughe ìhè. Arọ molekụla = 7.95; Specificgravity (H2O:1)=0.78; Ebe esi mmiri = 850 ℃ (decomposes n'okpuru BP); Ebe na-agbaze/na-agbaze = 689 ℃; Okpomọkụ akpaaka = 200 ℃. Identification Hazard (dabere na NFPA-704 M Rating System): Health 3, Flammability 4, Reactivity 2. Ihe siri ike na-ere ọkụ nke nwere ike ịmepụta ígwé ojii ikuku nke nwere ike ịgbawa na kọntaktị na ire ọkụ, okpomọkụ, ma ọ bụ oxidizers.

Njirimara ngwaahịa

Lithium hydride (LiH) bụ ihe nnu kristal (cubic na-eche ihu) nke na-acha ọcha n'ụdị ya dị ọcha, Dị ka ihe injinia, ọ nwere njirimara nke mmasị na ọtụtụ teknụzụ. Dịka ọmụmaatụ, ọdịnaya hydrogen dị elu na ịdị arọ nke LiH na-eme ka ọ baa uru maka ọta neutron na ndị nhazi na ụlọ ọrụ ike nuklia. Tụkwasị na nke ahụ, okpomọkụ dị elu nke ngwakọta jikọtara ya na ịdị arọ dị arọ na-eme ka LiH kwesịrị ekwesị maka mgbasa ozi nchekwa okpomọkụ maka ike anyanwụ na satellites ma nwee ike iji ya mee ihe dị ka ikpo ọkụ maka ngwa dị iche iche. Na-emekarị, usoro maka mmepụta nke LiH gụnyere ijikwa LiH na okpomọkụ karịa ebe mgbaze ya (688 DC). Ụdị 304L igwe anaghị agba nchara na- tinye n'ọrụ maka ọtụtụ usoro components ijikwa gbazee LiH.

Lithium hydride bụ ihe na-ahụkarị ionic hydride na lithium cations na hydride anions. Electrolysis nke ihe a wụrụ awụ na-arụpụta nguzobe nke lithium metal na cathode na hydrogen na anode. Mmeghachi omume mmiri lithium hydride, nke na-ebute ntọhapụ nke hydrogen gas, bụkwa ihe na-egosi hydrogen na-adịghị mma.

Lithium hydride bụ ihe na-acha ọcha na-acha ntụ ntụ, translucent, siri ike ma ọ bụ ntụ ntụ na-enweghị isi nke na-agba ọchịchịrị ngwa ngwa mgbe ikpughe ìhè. Lithium hydride dị ọcha na-etolite enweghị agba, kristal cubic. Ngwaahịa azụmaahịa nwere akara adịghị ọcha, dịka ọmụmaatụ, ọla lithium na-emebeghị ya, yabụ na-acha ntụ ntụ ma ọ bụ na-acha anụnụ anụnụ. Lithium hydride na-ekpo ọkụ nke ukwuu, ebe ọ bụ naanị ionic hydride na-agbaze na-enweghị ire ere na nrụgide ikuku (mp 688 ℃). N'adịghị ka ndị ọzọ alkali metal hydrides, lithium hydride bụ ubé soluble na inert pola organic solvents dị ka ethers. Ọ na-etolite ngwakọta eutectic na ọnụ ọgụgụ dị ukwuu nke nnu. Lithium hydride kwụsiri ike n'ikuku akọrọ mana ọ na-enwu na oke okpomọkụ. Na ooh ikuku ọ na-hydrolyzed exothermically; ihe kewara nke ọma nwere ike ịgbanwuo ozugbo. N'ebe okpomọkụ dị elu, ọ na-eji oxygen na-emeghachi omume iji mepụta lithium oxide, na nitrogen na-emepụta lithium nitride na hydrogen, na carbon dioxide na-emepụta lithium formate.
