Lithium hydride CAS 7580-67-8 99% maʻemaʻe ma ke ʻano he mea hōʻemi.
Hōʻike huahana
ʻO ka Lithium hydride he keʻokeʻo keʻokeʻo i ka hina, translucent, paʻa ʻole a i ʻole ka pauka keʻokeʻo e pōʻeleʻele koke i ka ʻike ʻana i ka mālamalama. Kaumaha molekula = 7.95; Kaumaha kiko (H2O:1)=0.78; Ka helu paila = 850 ℃ (decomposes ma lalo o BP); Puni haua / hehee = 689 ℃; Ka wela hoʻā ʻana = 200 ℃. Hōʻike Hazard (e pili ana i ka Pūnaehana Hoʻohālikelike NFPA-704 M): Ola 3, Flammability 4, Reactivity 2. He paʻa paʻa i hiki ke hana i nā ao o ka lewa e hiki ke pahū i ka pili ʻana me ka lapalapa, wela, a i ʻole nā mea hoʻoheheʻe.
Nā Waiwai Huahana
ʻO ka Lithium hydride (LiH) he mea paʻakai crystalline (kubiki i waena o ka maka) he keʻokeʻo i kona ʻano maʻemaʻe, Ma ke ʻano he mea ʻenekinia, loaʻa iā ia nā waiwai hoihoi i nā ʻenehana he nui. No ka laʻana, ʻo ka ʻike hydrogen kiʻekiʻe a me ke kaumaha māmā o LiH he mea pono ia no nā pale neutron a me nā mea hoʻoponopono i nā mea kanu nuklea. Eia kekahi, ʻo ka wela kiʻekiʻe o ka fusion i hui pū ʻia me ke kaumaha māmā e kūpono i ka LiH no ka media mālama wela no nā mea kanu mana o ka lā ma nā satellite a hiki ke hoʻohana ʻia ma ke ʻano he wela wela no nā noi like ʻole. ʻO ka maʻamau, ʻo nā kaʻina hana no ka hana ʻana o LiH e pili ana i ka lawelawe ʻana i ka LiH ma nā mahana ma luna o kona wahi heheʻe (688 DC). Hoʻohana ʻia ke kila kila kila ʻano 304L no nā ʻāpana kaʻina hana e lawelawe ana i ka LiH i hoʻoheheʻe ʻia.
ʻO Lithium hydride kahi hydride ionic maʻamau me nā cation lithium a me nā anion hydride. ʻO ka electrolysis o nā mea i hoʻoheheʻe ʻia i ka hoʻokumu ʻana i ka metala lithium ma ka cathode a me ka hydrogen ma ka anode. ʻO ka hopena lithium hydride-wai, ka hopena i ka hoʻokuʻu ʻia ʻana o ke kinoea hydrogen, he hōʻike pū kekahi i kahi hydrogen i hoʻopiʻi ʻia.
ʻO ka Lithium hydride he keʻokeʻo keʻokeʻo i ka hina, translucent, ʻaʻala ʻole a i ʻole ka pauka keʻokeʻo e pōʻeleʻele koke i ka ʻike ʻana i ka mālamalama. Hoʻokumu ʻia ka lithium hydride maʻemaʻe i nā kala kala ʻole, cubic crystals. Aia i loko o ka huahana kalepa nā ʻāpana o nā haumia, no ka laʻana, metala lithium i hoʻokō ʻole ʻia, a no laila he hina a uliuli paha. Paʻa loa ka Lithium hydride, ʻo ia wale nō ka ionic hydride e hoʻoheheʻe ʻole me ka palaho ʻole i ke kaomi lewa (mp 688 ℃). ʻOkoʻa me nā hydride metala alkali ʻē aʻe, hiki ke hoʻoheheʻe ʻia ka lithium hydride i loko o nā mea hoʻoheheʻe polar organik e like me ka ethers. Hoʻokumu ia i nā huila eutectic me ka nui o nā paʻakai. Paʻa ka Lithium hydride i ka ea maloʻo akā e ʻā ana i ka piʻi ʻana o ka mahana. I loko o ka ea mākū ua hydrolyzed exothermically; hiki ke ʻā wale nā mea i māhele ʻia. I ka wela kiʻekiʻe, hana ia me ka oxygen e hana i ka lithium oxide, me ka nitrogen e hana i ka lithium nitride a me ka hydrogen, a me ka carbon dioxide e hana i ka lithium formate.
Palapala noi
Hoʻohana ʻia ka Lithium hydride i ka hana ʻana o ka lithium alumini hydride a me ka silane, ma ke ʻano he mea hoʻohaʻahaʻa ikaika, ma ke ʻano he condensationagent i ka synthesis organik, ma ke ʻano he kumu lawe o ka hydrogen, a ma ke ʻano he mea pale pale nuklea māmā. Ke hoʻohana ʻia nei ia no ka mālama ʻana i ka ikehu wela no nā ʻōnaehana spacepower.
ʻO ka Lithium hydride kahi aniani keʻokeʻo polū-keʻokeʻo hiki ke puhi i ka wai. Hoʻohana ʻia i kumu o ke kinoea hydrogen i hoʻokuʻu ʻia ke lilo ʻo LiH i pulu. ʻO LiH kahi mea hoʻoheheʻe maikaʻi a me ka mea hoʻohaʻahaʻa a me kahi pale e pale ai mai ka radiation i hana ʻia e nā hopena nuklea.
Hoʻopaʻa a mālama
Hoʻopili: 100g/ tin can; 500g/ tin kini; 1kg no ke kinikini; 20kg no ka pahu hao
Ka Waihona: Hiki ke mālama ʻia i loko o nā kini metala me ka uhi waho no ka pale ʻana, a i ʻole i loko o nā pahu metala e pale ai i ka pōʻino mechanical. E kūʻai ma kahi kaʻawale, ʻoluʻolu, maloʻo a me ka makani maikaʻi, a pale pono i ka makū. Pono nā hale e hoʻoheheʻe maikaʻi ʻia a ʻaʻole i hoʻopaʻa ʻia i ke kinoea.
