Lithium hydride foda ne mai launin fari zuwa launin toka, mai haske, mara wari, mai ƙarfi ko fari wanda ke yin duhu da sauri idan aka fallasa shi ga haske. Nauyin kwayoyin halitta = 7.95; Nauyin nauyi na musamman (H2O:1) = 0.78; Wurin tafasa = 850℃ (yana narkewa a ƙasa da BP); Wurin daskarewa/Narkewa = 689℃; Zafin jiki na atomatik = 200℃. Gano Haɗari (bisa Tsarin Matsayin NFPA-704 M): Lafiya 3, Ikon ƙonewa 4, Amsawa 2. Ƙarfin da zai iya ƙonewa wanda zai iya samar da gajimare na ƙurar iska wanda zai iya fashewa idan aka taɓa shi da harshen wuta, zafi, ko masu tace iska.

Lithium hydride (LiH) wani sinadari ne mai gishiri mai lu'ulu'u (mai siffar cubic) wanda yake da launin fari a cikin siffarsa ta zahiri. A matsayin kayan injiniya, yana da halaye masu ban sha'awa a cikin fasahohi da yawa. Misali, yawan sinadarin hydrogen da nauyin LiH mai sauƙi suna sa ya zama da amfani ga garkuwar neutron da masu daidaitawa a cikin tashoshin wutar lantarki na nukiliya. Bugu da ƙari, yawan zafin da aka haɗa tare da nauyi mai sauƙi yana sa LiH ya dace da kafofin adana zafi don tashoshin wutar lantarki na hasken rana akan tauraron dan adam kuma ana iya amfani da shi azaman wurin nutsewa don aikace-aikace daban-daban. Yawanci, hanyoyin samar da LiH sun haɗa da sarrafa LiH a yanayin zafi sama da wurin narkewa (688 DC). Ana amfani da nau'in ƙarfe mai bakin ƙarfe 304L don abubuwan sarrafawa da yawa da ke sarrafa LiH mai narkewa.
Lithium hydride wani nau'in ionic hydride ne da aka saba da shi wanda ke ɗauke da lithium cations da hydride anions. Electrolysis na kayan da aka narke yana haifar da samuwar ƙarfe na lithium a cathode da hydrogen a anode. Haɗakar lithium hydride-ruwa, wanda ke haifar da sakin iskar hydrogen, shi ma yana nuna cewa hydrogen yana da caji mara kyau.
Lithium hydride foda ne mai launin fari zuwa launin toka, mai haske, mara wari, wanda ke yin duhu cikin sauri idan aka fallasa shi ga haske. Tsarkakken lithium hydride yana samar da lu'ulu'u masu siffar kubik, marasa launi. Samfurin da ake sayarwa ya ƙunshi alamun ƙazanta, misali, ƙarfen lithium wanda ba ya amsawa, kuma saboda haka launin toka mai haske ko shuɗi ne. Lithium hydride yana da ƙarfi sosai a yanayin zafi, kasancewarsa hydride na ionic kaɗai da ke narkewa ba tare da ruɓewa ba a matsin yanayi (mp 688 ℃). Sabanin sauran hydride na ƙarfe alkali, lithium hydride yana narkewa kaɗan a cikin abubuwan narkewa na halitta marasa aiki kamar ethers. Yana samar da gaurayawan eutectic tare da adadi mai yawa na gishiri. Lithium hydride yana da ƙarfi a cikin busasshiyar iska amma yana ƙonewa a lokacin da zafin ya ƙaru. A cikin iska mai danshi, ana samar da shi ta hanyar hydrolyzed ta hanyar exotherm; kayan da aka raba sosai na iya ƙonewa ta hanyar kwatsam. A yanayin zafi mai yawa, yana amsawa da oxygen don samar da lithium oxide, tare da nitrogen don samar da lithium nitride da hydrogen, da kuma tare da carbon dioxide don samar da lithium formate.
Aikace-aikace
Ana amfani da Lithium hydride wajen kera lithium aluminum hydride da silane, a matsayin mai rage ƙarfi, a matsayin mai sanyaya iska a cikin hadakar kwayoyin halitta, a matsayin tushen hydrogen mai ɗaukuwa, da kuma a matsayin kayan kariya na nukiliya mai sauƙi. Yanzu ana amfani da shi don adana makamashin zafi don tsarin wutar lantarki ta sararin samaniya.
Lithium hydride lu'ulu'u ne mai launin shuɗi-fari wanda ke iya kama da wuta a cikin danshi. Ana amfani da shi azaman tushen iskar hydrogen wanda ake saki lokacin da LiH ya jike. LiH kyakkyawan wakili ne na bushewa da rage zafi, haka kuma garkuwa ce da ke kare shi daga radiation da halayen nukiliya suka haifar.
Shiryawa & Ajiya
Marufi: 100g/gwangwani; 500g/gwangwani; 1kg/gwangwani; 20kg a kowace ganga ta ƙarfe
Ajiya: Ana iya adana shi a cikin gwangwanin ƙarfe mai murfin waje don kariya, ko kuma a cikin ganga na ƙarfe don hana lalacewar injiniya. A adana a wuri daban, mai sanyi, busasshe kuma mai iska mai kyau, kuma a hana danshi sosai. Gine-gine dole ne su kasance masu iska mai kyau kuma ba su da taruwar iskar gas.
