He aha ka Lanthanum Carbonate a me kāna noi, kala?

Lanthanum carbonate(lanthanum carbonate), ʻano mole mole no La2 (CO3) 8H2O, maʻamau i loaʻa kekahi nui o nā molekole wai. ʻO ia ka rhombohedral crystal system, hiki ke hana me ka hapa nui o nā waikawa, solubility 2.38 × 10-7mol / L i ka wai ma 25 ° C. Hiki ke hoʻoheheʻe ʻia i ka lanthanum trioxide ma 900°C. I ke kaʻina hana o ka thermal decomposition, hiki iā ia ke hana i ka alkali. I ke kaʻina o ka thermal decomposition hiki ke hana i ka alkali.Lanthanum carbonatehiki ke hana ʻia me nā carbonate metala alkali e hana i ka paʻakai paʻakai paʻakai paʻakai.Lanthanum carbonateHiki ke hana ʻia ka wai ma ka hoʻohui ʻana i ka ammonium carbonate i loko o ka hopena dilute o ka paʻakai lanthanum hiki ke hoʻoheheʻe ʻia.

Ka nana aku:: Pauka keʻokeʻo a waihoʻoluʻu ʻole, hiki ke hoʻoheheʻe ʻia i loko o ka waikawa, paʻa i ka ea.

Hoʻohana:.Lanthanum carbonatehe hui anoano i haku ia me ka mea lanthanum a me ka carbonate ion. Hōʻike ʻia ia e ka paʻa ikaika, haʻahaʻa haʻahaʻa a me nā waiwai kemika ikaika. I ka ʻoihana, hiki ke hoʻohana nui ʻia ka lanthanum carbonate i nā ceramics, electronics, medicine and other fields. Ma waena o lākou, he kuleana koʻikoʻi ka lanthanum carbonate i ka ʻoihana seramika, hiki ke hoʻohana ʻia e like me ka puaʻa, glaze, nā mea hoʻohui aniani, etc.; i ke kahua o ka uila, hiki ke hoʻomākaukau ʻia ka lanthanum carbonate me ka conductivity uila kiʻekiʻe, ka sintering haʻahaʻa haʻahaʻa o nā mea ikaika, kūpono no ka hana ʻana i nā capacitors kiʻekiʻe-ʻike, hoʻohana ʻia i ka hana ʻana i nā catalysts ternary, nā mea hoʻohui carbide cemented; ma ke kahua o nā lāʻau lapaʻau,lanthanum carbonatehe mea hoʻohui maʻamau i nā lāʻau lapaʻau, a hiki ke hoʻohana ʻia no ka mālama ʻana i ka lāʻau lapaʻau,lanthanum carbonatehe mea hoʻohui lāʻau maʻamau, hiki ke hoʻohana ʻia no ka mālama ʻana i ka hypercalcemia, hemolytic uremic syndrome a me nā maʻi ʻē aʻe, a he kūpono ia no ka mālama ʻana i ka hyperphosphatemia i nā maʻi maʻi renal hope. Ma kahi huaʻōlelo,lanthanum carbonateHe nui nā hana a hoʻohana nui ʻia i ka ʻoihana kemika hou, ʻepekema waiwai, lāʻau lapaʻau a me nā ʻano ʻē aʻe.

Hoʻopili: 25, 50/kg, 1000kg/tonne i ka ʻeke i ulana ʻia, 25, 50kg/barela i ka pahu pahu pahu.

Pehea e hana ai:

Lanthanum carbonateʻo ia ka hui nui no ka hana ʻana i ka lanthanum oxide [1-4]. Me ke kūlana koʻikoʻi o ka mālama ʻana i ke kaiapuni, ʻo ka ammonium bicarbonate, ma ke ʻano he precipitant kuʻuna no ka hoʻomākaukau ʻana i ka lanthanum carbonate, ua hoʻohana nui ʻia i ka hana ʻenehana [5-7], ʻoiai ʻo ia nā mea maikaʻi o ka haʻahaʻa haʻahaʻa o ka hana a me ka haʻahaʻa haʻahaʻa haumia. o ka carbonate i loaa. Eia nō naʻe, ma muli o ka eutrophication o NH + 4 i loko o ka wai ʻōpala ʻoihana, ʻoi aku ka nui o ka hopena i ke kaiapuni, ua kau ʻia ka nui o nā paʻakai ammonium i hoʻohana ʻia i ka ʻoihana. E like me kekahi o ka nui precipitants, sodium carbonate, i hoohalikeia me ka ammonium bicarbonate, i ka hoomakaukau ana olanthanum carbonate in ke kaʻina o ka wai ʻino ʻoihana me ka amonia ʻole, nā haumia nitrogen, maʻalahi ke hana ʻana; ke hoʻohālikelike ʻia me ka sodium bicarbonate, hoʻololi i ke kaiapuni he ikaika [8 ~ 11].Lanthanum carbonateme ka sodium carbonate ma ke ʻano he precipitant no ka hoʻomākaukau ʻana i ka low-sodium rare earth carbonate i kakaikahi i hōʻike ʻia ma ka palapala, e lawe ana i ke kumu kūʻai haʻahaʻa a me ka maʻalahi o ke ʻano o ka ua.lanthanum carbonateua hoʻomākaukau ʻia ma ka hoʻomalu ʻana i ke ʻano o ka hopena.

Hoʻomalu no ka lawe ʻana olanthanum carbonate: Pono e hoʻolako ʻia nā kaʻa kaʻa me nā ʻano kūpono a me ka nui o nā lako ahi a me nā lako lapaʻau ulia pōpilikia. Hoʻopaʻa loa ʻia ka hui ʻana a me ka lawe ʻana me nā oxidizers a me nā kemika hiki ke ʻai. Pono e hoʻolako ʻia ka paipu pauku o ke kaʻa lawe ukana me ka pale ahi. Ke hoʻohana ʻia nā kaʻa moku no ka lawe ʻana, pono e hoʻokomo ʻia nā kaulahao lepo. I mea e hōʻemi ai i ka uila static i hana ʻia e ka vibration, hiki ke hoʻokomo i nā mea hoʻokaʻawale puka i loko o ka pahu. ʻAʻole ʻae ʻia ka hoʻouka ʻana a i ʻole ka hoʻouka ʻana i nā mea hana mechanical a me nā mea hana e pili ana i nā huna ahi. I ke kauwela kakahiaka a me ke ahiahi maikaʻi ka lawe ʻana, ma ke kaʻina hana, e pale aku i ka lā a me ka ua a me ka wela kiʻekiʻe. E noho mamao mai ke kumu ahi, ke kumu wela a me ka wahi wela kiʻekiʻe i ka wā hoʻomaha. Pono e hoʻokō ʻia ka halihali alanui e like me nā ala i kuhikuhi ʻia, a ʻaʻole pono e kū ma nā wahi noho a me nā wahi paʻa. ʻAʻole ʻae ʻia ke kaʻa ʻana o ke kaʻaahi. Ua pāpā loa ʻia ka lawe ʻana i ka nui ma nā moku lāʻau a i ʻole nā ​​moku sima. E kau ʻia nā hōʻailona pōʻino a me nā hoʻolaha ma luna o nā ala kaʻa e like me nā koi o ka halihali.

Nā hōʻailona kino a me kemika (%).

Nānā: Hiki ke hana ʻia nā huahana a hoʻopaʻa ʻia e like me nā kikoʻī o ka mea hoʻohana.
