Litiyumu hydride CAS 7580-67-8 99% isuku nkigabanya imiti
Ibisobanuro ku bicuruzwa
Litiyumu hydride ni yera-yera yijimye, yoroheje, impumuro nziza cyangwa ifu yera yijimye vuba iyo ihuye numucyo. Uburemere bwa molekuline = 7.95; Ubusobanuro bwihariye (H2O: 1) = 0,78; Ingingo yo guteka = 850 ℃ (decomposesbelow BP); Gukonjesha / Gushonga ingingo = 689 ℃; Autoignitiontemperature = 200 ℃. Kumenyekanisha Ibyago (bishingiye kuri Sisitemu yo Kuringaniza NFPA-704 M): Ubuzima 3, Flammability 4, Reactivite 2. Ikomeye yaka ishobora gukora ibicu biva mu kirere bishobora guturika bihuye numuriro, ubushyuhe, cyangwa okiside.
Ibicuruzwa
Litiyumu hydride (LiH) nikintu cyumunyu wa kirisiti (cubic-centre-cubic) cyera muburyo bwera, Nkibikoresho byubwubatsi, bifite inyungu zubuhanga bwinshi. Kurugero, hydrogène nyinshi hamwe nuburemere bworoshye bwa LiH bituma igira akamaro ingabo za neutron hamwe nabayobora mumashanyarazi ya kirimbuzi. Byongeye kandi, ubushyuhe bwinshi bwo guhuza hamwe nuburemere bworoheje bituma LiH ikwiranye nububiko bwo kubika ubushyuhe bwamashanyarazi akomoka ku mirasire yizuba kuri satelite kandi birashobora gukoreshwa nkicyuma gishyuha mubikorwa bitandukanye. Mubisanzwe, inzira yo gukora LiH ikubiyemo gufata LiH mubushyuhe burenze aho yashonga (688 DC). Andika 304L ibyuma bidafite ingese bikoreshwa mubice byinshi bitunganya LiH yashongeshejwe.
Litiyumu hydride ni hydride isanzwe ya ionic hamwe na lithium cations hamwe na hydride anion. Electrolysis yibintu byashongeshejwe bivamo gukora icyuma cya lithium kuri cathode na hydrogen kuri anode. Lithium hydride-water reaction, bivamo gusohora gaze ya hydrogène, nayo irerekana hydrogène yuzuye nabi.
Litiyumu hydride ni yera-yera yijimye, yoroheje, impumuro nziza cyangwa ifu yera yijimye vuba iyo ihuye numucyo. Hydride yuzuye ya lithium ikora ibara ritagira ibara, kristu ya cubic. Ibicuruzwa byubucuruzi birimo ibimenyetso byumwanda, urugero, icyuma cya lithium idakozwe, bityo rero ni ibara ryerurutse cyangwa ubururu. Litiyumu hydride ihagaze neza cyane, niyo hydride yonyine ya ionic ishonga nta kubora kumuvuduko wikirere (mp 688 ℃). Bitandukanye nibindi byuma bya alkali, hydride ya lithium irashonga gato muri inert polar organic solver nka ethers. Ikora eutectic ivanze numubare munini wumunyu. Litiyumu hydride ihagaze neza mumuyaga wumye ariko ikongeza ubushyuhe bwiyongereye. Mu kirere cyuzuye ni hydrolyzed mu buryo butemewe; ibikoresho bigabanijwe neza birashobora gutwika ubwabyo. Ubushyuhe bwo hejuru, ifata ogisijeni ikora lisiyumu ya lithium, hamwe na azote ikora nitride ya lithium na hydrogène, hamwe na dioxyde de carbone ikora lithium.
Gusaba
Litiyumu hydride ikoreshwa mugukora lithium aluminium hydride na silane, nkibikoresho bigabanya imbaraga, nka condensationagent muri synthesis organique, nkibikoresho bya hydrogène, kandi nkibikoresho birinda kirimbuzi byoroheje. Ubu irakoreshwa mukubika ingufu zubushyuhe bwa sisitemu yo mu kirere.
Litiyumu hydride ni kirisiti yubururu-yera yaka cyane. Ikoreshwa nkisoko ya gaze ya hydrogen irekurwa iyo LiH ihindutse. LiH nikintu cyiza cyane kandi kigabanya imbaraga kimwe ningabo ikingira imirase iterwa ningaruka za kirimbuzi.
Gupakira & Ububiko
Gupakira: 100g / amabati arashobora; 500g / amabati arashobora; 1kg kuri tin ishobora; 20kg ku ngoma y'icyuma
Ububiko: Irashobora kubikwa mumabati yicyuma hamwe nigifuniko cyo hanze kugirango ikingire, cyangwa mungoma zicyuma kugirango birinde kwangirika. Bika ahantu hatandukanye, hakonje, humye kandi uhumeka neza, kandi wirinde rwose ubuhehere. Inyubako zigomba guhumeka neza kandi muburyo butarimo kwirundanya gaze.
