Lithium hydride CAS 7580-67-8 99% kuchena semushonga wekuderedza
Tsananguro yeChigadzirwa
Lithium hydride ipfunde isina kuchena kusvika kugrey, inopenya, isina hwema, inosviba nekukurumidza kana yaiswa muchiedza. Kurema kwemasero = 7.95; Huremu hwegiravhiti (H2O:1)=0.78; Pokufashaira = 850℃ (inoora pasi peBP); Pokutonhora/Kunyunguduka = 689℃; Tembiricha yekuzvipisa = 200℃. Kuzivikanwa kweHazard (zvichibva paNFPA-704 M Rating System): Hutano 3, Kupisa 4, Reactivity 2. Chinhu chakasimba chinobvira chinogona kugadzira makore eguruva remumhepo anogona kuputika kana akabatana nemurazvo, kupisa, kana oxidizers.
Zvivakwa zveChigadzirwa
Lithium hydride (LiH) chinhu chine munyu wakaita sekristaro (cubic iri pakati pechiso) chichena muchimiro chayo chakachena, Sechinhu cheinjiniya, ine hunhu hunonakidza mune matekinoroji akawanda. Semuenzaniso, huwandu hwakawanda hwehydrogen uye huremu hushoma hweLiH zvinoita kuti ishande kune neutron shield uye moderators muzviteshi zvemagetsi zvenyukireya. Pamusoro pezvo, kupisa kwakanyanya kwefusion pamwe nehuremu hushoma zvinoita kuti LiH ive yakakodzera kuchengetera kupisa kwezviteshi zvemagetsi ezuva pamasetiraiti uye inogona kushandiswa se heat sink kune mashandisirwo akasiyana. Kazhinji, maitiro ekugadzira LiH anosanganisira kubata LiH patembiricha iri pamusoro penzvimbo yayo yekunyunguduka (688 DC). Simbi isina tsvina yemhando ye304L inoshandiswa kune akawanda ma process components anobata LiH yakanyungudutswa.
Lithium hydride imhando yeionic hydride ine lithium cations uye hydride anions. Kugadziriswa kweelectrolysis yezvinhu zvakanyungudutswa kunoita kuti lithium metal iumbwe pa cathode uye hydrogen pa anode. Kugadziriswa kwe lithium hydride-water, uko kunoita kuti hydrogen iburitswe, kunoratidzawo kuti hydrogen haina simba rakawanda.
Lithium hydride ipfuu yakasimba kana chena isina kuchena kubva pachena kuenda kugrey, inopenya, isina hwema, inosviba nekukurumidza kana yaiswa muchiedza. Lithium hydride yakachena inoumba makristaro e cubic asina ruvara. Chigadzirwa ichi chine zvisaririra zvetsvina, semuenzaniso, lithium metal isina kugadziriswa, uye nekudaro ine grey kana bhuruu yakapfava. Lithium hydride yakasimba kwazvo pakupisa, ichiva iyo chete ionic hydride inonyunguduka isina kuora pakumanikidzwa kwemhepo (mp 688 ℃). Kusiyana nedzimwe alkali metal hydride, lithium hydride inonyunguduka zvishoma mu inert polar organic solvents senge ethers. Inogadzira eutectic mixtures ine munyu wakawanda. Lithium hydride inogara mumhepo yakaoma asi inobatidza pakupisa kwakawedzera. Mumhepo ine hunyoro inobatidzwa ne hydrolyzed exothermically; zvinhu zvakakamurwa zvakanaka zvinogona kupisa zvoga. Pakupisa kwakakwira, inobatana ne oxygen kugadzira lithium oxide, ne nitrogen kugadzira lithium nitride ne hydrogen, uye ne carbon dioxide kugadzira lithium formate.
Kushandiswa
Lithium hydride inoshandiswa mukugadzirwa kwe lithium aluminium hydride uye silane, sechinhu chinodzikisa simba, sechinhu chinonyungudutsa mukugadzirwa kwe organic, sechinhu chinotakurika chehydrogen, uye sechinhu chinodzivirira nyukireya. Iye zvino chiri kushandiswa kuchengetedza simba rekupisa remagetsi emuchadenga.
Lithium hydride ikristaro chena-bhuruu inobvira kana iri munyoro. Inoshandiswa senzvimbo yegesi rehydrogen rinobuda kana LiH yanyorova. LiH imushonga wakanaka wekubvisa makemikari uye unodzikisa makemikari pamwe nekudzivirira kubva kumwaranzi inogadzirwa ne nuclear reactions.
Kurongedza & Kuchengeta
Kurongedza: 100g/ gaba resimbi; 500g/ gaba resimbi; 1kg pagaba resimbi; 20kg padhiramu resimbi
Kuchengetera: Inogona kuchengetwa mumagaba esimbi ane chifukidziro chekunze chekudzivirira, kana mumadhiramu esimbi kudzivirira kukuvara kwemuchina. Chengeta munzvimbo yakasiyana, inotonhorera, yakaoma uye ine mhepo yakanaka, uye dzivirira hunyoro zvakanyanya. Zvivako zvinofanirwa kunge zvine mhepo yakanaka uye zvisina kuungana kwegasi.
