Lithium hydride CAS 7580-67-8 99% kuchena seanoderedza mumiririri
Product Description
Lithium hydride ichena-chena kusvika kune greyish, inopenya, isina kunhuhwirira yakasimba kana chena poda inosviba nekukasira pakuratidzwa nechiedza. Molecular uremu = 7.95; Specificgravity (H2O:1)=0.78; Boiling point = 850 ℃ (inoora pazasi BP); Kutonhodza/Kunyungudika = 689℃; Autoignitiontemperature = 200 ℃. Hazard Identification (yakavakirwa paNFPA-704 M Rating System): Hutano 3, Kupisa 4, Reactivity 2. Chinhu chinopisa chinogona kuumba makore anokonzerwa nemhepo anogona kuputika kana asangana nemurazvo, kupisa, kana oxidizer.
Product Properties
Lithium hydride (LiH) chinhu checrystalline munyu (face-centered cubic) iyo chena mune yayo yakachena fomu, Sechinhu cheinjiniya, ine zvimiro zvekufarira mune akawanda matekinoroji. Semuenzaniso, iyo yakakwira hydrogen yemukati uye huremu huremu hweLiH hunoita kuti ive yakakosha kune neutron nhoo uye mamodhireta mumagetsi enyukireya. Pamusoro pezvo, kupisa kwakanyanya kwekusanganiswa kwakasanganiswa nehuremu huremu hunoita LiH inokodzera kupisa midhiya yemagetsi emagetsi ezuva pamasatelliti uye inogona kushandiswa sedhishi yekupisa kune akasiyana maapplication. Kazhinji, maitiro ekugadzirwa kweLiH anosanganisira kubata kweLiH pane tembiricha iri pamusoro pekunyungudika kwayo (688 DC). Type 304L simbi isina tsvina inoshandiswa kune akawanda ma process ezvikamu zvinobata yakanyungudutswa LiH.
Lithium hydride inowanzoitika ionic hydride ine lithium cations uye hydride anions. Electrolysis yezvinhu zvakanyungudutswa zvinokonzeresa kuumbwa kwelithium simbi pane cathode uye hydrogen pane anode. Iyo lithium hydride-water reaction, iyo inoguma nekubudiswa kwehydrogen gasi, inoratidzawo yehaidhirojeni yakashata.
Lithium hydride ichena-chena kune greyish, inopenya, isina kunhuhwirira yakasimba kana chena poda inosviba nekukasira pakuratidzwa nechiedza. Yakachena lithium hydride inoumba isina ruvara, cubic crystals. Chigadzirwa chekutengesa chine zvisaririra zvetsvina, semuenzaniso, isina kubatwa lithium simbi, uye nekudaro inopenya grey kana yebhuruu. Lithium hydride yakagadzikana zvakanyanya, ichiva iyo chete ionic hydride inonyungudika isina kuora pamhepo yemhepo (mp 688 ℃). Kusiyana nedzimwe alkali metal hydrides, lithium hydride inonyungudika zvishoma muinert polar organic solvents senge ethers. Iyo inoumba eutectic musanganiswa nenhamba yakawanda yemunyu. Lithium hydride inogadzikana mumhepo yakaoma asi inobatidza pakuwedzera tembiricha. Mumhepo yakanyorova ine hydrolyzed exothermically; zvinhu zvakakamurwa zvakanaka zvinogona kungobatidza zvoga. Pakupisa kwepamusoro, inopindirana neokisijeni kuumba lithium oxide, nenitrogen kuumba lithium nitride nehydrogen, uye necarbon dioxide kuumba lithium formate.
Application
Lithium hydride inoshandiswa mukugadzira lithium aluminium hydride uye silane, seine simba rekudzikisa mumiririri, seyakagadziriswa muorganic synthesis, sechinhu chinotakurika chehydrogen, uye seyakareruka nyukireya inodzivirira zvinhu. Ikozvino yave kushandiswa kuchengetedza simba rekupisa kune spacepower masisitimu.
Lithium hydride ikristaro ine bluish-chena inopfuta mukunyorova. Inoshandiswa sesosi yehydrogen gasi inosunungurwa kana LiH yanyorova. LiH yakanakisa desiccant uye inoderedza mumiriri pamwe nenhoo inodzivirira kubva kumwaranzi inogadzirwa nekuita kwenyukireya.
Kurongedza & Kuchengeta
Kurongedza: 100g / tin can; 500g / gaba; 1kg per gaba; 20kg padhiramu resimbi
Kuchengeta: Inogona kuchengetwa mumagaba esimbi ane chivharo chekunze chekudzivirira, kana mumadhiramu esimbi kudzivirira kukuvadzwa kwemichina. Chengetedza munzvimbo yakaparadzana, inotonhorera, yakaoma uye inofefetera zvakanaka, uye kudzivirira unyoro. Zvivakwa zvinofanirwa kunge zvichifefeterwa zvakanaka uye zvisina gasi kuunganidzwa.
