Lithium hydride CAS 7580-67-8 99% daahirnimo sida wakiilka yaraynta
Sharaxaada Alaabta
Lithium hydride waa caddaan-ka-baxa cawlan, dhalaalaysa, adag ama budo cad oo aan ur lahayn oo si degdeg ah u madoobaata marka ay iftiinku gaadho. Miisaanka molecular = 7.95; Cufis-jiideedka gaarka ah (H2O:1)=0.78; Barta karkarinta = 850 ℃ (ka hooseeya BP); Barafka qaboojinta/dhalaalida = 689℃; Heerkulka tooska ah = 200 ℃. Aqoonsiga Khatarta (oo ku salaysan NFPA-704 M Nidaamka Qiimaynta): Caafimaadka 3, Daboolista 4, Falcelinta 2. Adag guban kara oo samayn kara daruuro hawadu hawada ka soo baxay oo laga yaabo inay ku qarxaan taabashada ololka, kulaylka, ama oksaydhiyeyaasha.
Guryaha Alaabta
Lithium hydride (LiH) waa walax milix ah (cubic waji ku salaysan) oo cad qaabkeeda saafiga ah, Maaddada injineernimada, waxay leedahay sifooyin xiiso leh tignoolajiyada badan. Tusaale ahaan, waxa ku jira haydaroojiin sare iyo miisaanka fudud ee LiH ayaa ka dhigaya mid faa'iido u leh gaashaanka neutronka iyo dhexdhexaadiyeyaasha dhirta tamarta nukliyeerka. Intaa waxaa dheer, kulaylka sare ee fiyuuska oo lagu daray miisaanka fudud wuxuu ka dhigayaa LiH ku habboon warbaahinta kaydinta kulaylka ee dhirta tamarta qoraxda ee satalaytka waxaana laga yaabaa in loo isticmaalo kuleylka kuleylka codsiyada kala duwan. Caadi ahaan, hababka wax soo saarka LiH waxay ku lug leeyihiin maaraynta LiH heerkulka ka sarreeya barta dhalaalka (688 DC). Nooca 304L birta aan lahayn waxaa loo isticmaalaa qaybo badan oo ka mid ah hababka maaraynta LiH dhalaalaysa.
Lithium hydride waa hydride caadiga ah ee ionic leh cations lithium iyo anions hydride. Electrolysis ee alaabta dhalaalaysa waxay keentaa samaynta birta lithium ee cathode iyo hydrogen ee anode. Falcelinta biyaha lithium-hydride, taas oo keenta sii deynta gaasta hydrogen, sidoo kale waxay tilmaan u tahay hydrogen si taban
Lithium hydride waa caddaan-ka-baxsan cawlan, dhalaalaysa, adag ama budo cad oo aan ur lahayn oo si degdeg ah u madoobaata marka ay iftiinka soo gaadho. Lithium hydride saafi ah waxa ay samaysaa bilaa midab, kiristaalo cubic. Badeecada ganacsigu waxa ay ka kooban tahay raadad wasakh ah, tusaale ahaan, birta lithium-ka oo aan falcelin lahayn, oo sidaas awgeed waa cawl ama buluug khafiif ah. Lithium hydride waa kuleyl aad u deggan, isagoo ah hydride ionic kaliya ee dhalaaliya iyada oo aan la dumin cadaadiska atmospheric (mp 688 ℃). Si ka duwan kuwa kale ee hydrides biraha alkali, lithium hydride wax yar bay ku milmi kartaa dareerayaasha dabiiciga ah ee aan shaqaynayn sida ethers. Waxay samaysaa isku dhafka eutectic oo leh tiro badan oo cusbo ah. Lithium hydride waa ku xasiloon tahay hawo engegan laakiin waxay ku shidaysaa heerkulka sare. Hawo qoyan ayaa si heer sare ah loo nadiifiyaa; walxo si fiican u qaybsan ayaa si kedis ah u shidi kara. Heerkul sarreeya, waxay la falgashaa ogsijiin si ay u samayso lithium oxide, oo leh nitrogen si ay u samayso lithium nitride iyo hydrogen, iyo kaarboon dioxide si ay u samayso qaab lithium ah.
Codsiga
Lithium hydride waxaa loo isticmaalaa soo saarista lithium aluminium hydride iyo silane, sida wakiilka yaraynta awoodda leh, sida uumiga ee isku-dhafka organic, sida isha la qaadi karo ee hydrogen, iyo sida walxaha gaashaanka nukliyeerka fudud. Hadda waxa loo isticmaalaa kaydinta tamarta kulaylka ee nidaamyada tamarta hawada sare.
Lithium hydride waa kiristaalo buluug-caddaan ah oo qoyaanka ololaya. Waxa loo istcimaalaa isha gaasta haydaroojin ee la xoreeyo marka LiH qoyanto. LiH waa qallajiye heer sare ah iyo wakiil yareeya iyo sidoo kale gaashaan ka ilaaliya shucaaca uu abuuray falcelinta nukliyeerka.
Baakaynta & Kaydinta
Xirmooyinka: 100g / qasac; 500 g / qasacadaysan; 1kg halkii qasac; 20kg halkii durbaan bir ah
Kaydinta: Waxaa lagu kaydin karaa gasacadaha birta ah ee daboolka sare leh si loo ilaaliyo, ama durbaannada birta ah si looga hortago burbur farsamo. Ku kaydi meel gaar ah, qabow, qalalan oo hawo leh, si adagna uga ilaali qoyaanka. Dhismayaashu waa inay ahaadaan kuwo hawo fiican leh oo qaab dhismeedkoodu ka madax bannaan yahay gaas urursan.
