Kodi Lanthanum Carbonate ndi ntchito yake, mtundu?

Lanthanum carbonate(lanthanum carbonate), chilinganizo cha molekyulu cha La2 (CO3) 8H2O, nthawi zambiri chimakhala ndi kuchuluka kwa mamolekyu amadzi. Ndi rhombohedral crystal system, imatha kuchitapo kanthu ndi ma acid ambiri, kusungunuka kwa 2.38 × 10-7mol / L m'madzi pa 25 ° C. Ikhoza kuwola mwa kutentha kukhala lanthanum trioxide pa 900 ° C. Pakuwola kwa matenthedwe, imatha kupanga alkali. M`kati matenthedwe kuwonongeka akhoza kupanga zamchere.Lanthanum carbonateakhoza kupangidwa ndi alkali zitsulo carbonates kupanga madzi sungunuka carbonate zovuta mchere.Lanthanum carbonatempweya ukhoza kupangidwa powonjezera pang'ono ammonium carbonate ku njira yothetsera mchere wosungunuka wa lanthanum.

Dzina lazogulitsa:Lanthanum carbonate

Molecular formula:La2 (CO3) 3

Kulemera kwa maselo:457.85

CAS NO. :6487-39-4

Maonekedwe:: ufa woyera kapena wopanda mtundu, wosungunuka mosavuta mu asidi, wotsekemera.

Ntchito:.Lanthanum carbonatendi organic pawiri wopangidwa ndi lanthanum element ndi carbonate ion. Iwo yodziwika ndi amphamvu bata, otsika solubility ndi yogwira mankhwala katundu. M'makampani, lanthanum carbonate imatha kugwiritsidwa ntchito kwambiri muzoumba, zamagetsi, zamankhwala ndi zina. Pakati pawo, lanthanum carbonate imagwira ntchito yofunika kwambiri pamakampani a ceramics, angagwiritsidwe ntchito ngati pigment, glaze, zowonjezera magalasi, ndi zina zotero; m'munda wamagetsi, lanthanum carbonate ikhoza kukonzedwa ndi magetsi apamwamba kwambiri, kutentha kwapansi kutentha kwa zipangizo zamphamvu, zoyenera kupanga ma capacitor amphamvu kwambiri, omwe amagwiritsidwa ntchito popanga ternary catalysts, cemented carbide zowonjezera; m'munda wa pharmaceuticals,lanthanum carbonatendizowonjezera pamankhwala, ndipo zitha kugwiritsidwa ntchito pochiza Pazamankhwala,lanthanum carbonatendi wamba mankhwala zowonjezera, amene angagwiritsidwe ntchito zochizira hypercalcemia, hemolytic uremic syndrome ndi matenda ena, ndipo ndi oyenera zochizira hyperphosphatemia kumapeto-siteji aimpso odwala. M'mawu amodzi,lanthanum carbonateali ndi ntchito zambiri ndipo amagwiritsidwa ntchito kwambiri m'makampani amakono amankhwala, sayansi yazinthu, zamankhwala ndi zina.

Momwe mungapangire:

Lanthanum carbonatendiye chigawo chachikulu chopangira lanthanum oxide [1-4]. Ndi momwe zinthu zikuchulukirachulukira pakuteteza chilengedwe, ammonium bicarbonate, monga njira yopangira lanthanum carbonate, yakhala ikugwiritsidwa ntchito kwambiri popanga mafakitale [5-7], ngakhale ili ndi zabwino zake zotsika mtengo komanso zotsika zonyansa. wa carbonate wotengedwa. Komabe, chifukwa cha eutrophication ya NH + 4 m'madzi otayira m'mafakitale, omwe amakhudza kwambiri chilengedwe, kuchuluka kwa mchere wa ammonium womwe umagwiritsidwa ntchito m'makampaniwo kwayikidwa patsogolo zofunikira kwambiri. Monga mmodzi wa precipitants waukulu, sodium carbonate, poyerekeza ndi ammonium bicarbonate, pokonzalanthanum carbonate ndin njira yamadzi otayira m'mafakitale opanda ammonia, zonyansa za nayitrogeni, zosavuta kuthana nazo; poyerekeza ndi sodium bicarbonate, atengere chilengedwe ndi amphamvu [8~11].Lanthanum carbonatendi sodium carbonate monga precipitant yokonza otsika-sodium osowa dziko lapansi carbonate ndi kaŵirikaŵiri anafotokoza m'mabuku, amene utenga otsika mtengo, yosavuta ntchito yabwino kudyetsa mpweya njira, ndi otsika sodium.lanthanum carbonateimakonzedwa poyang'anira zinthu zingapo zomwe zimachitika.

Kusamala pamayendedwe alanthanum carbonate: Magalimoto oyendera ayenera kukhala ndi mitundu yoyenera ndi kuchuluka kwa zida zozimitsa moto ndi zida zadzidzidzi zomwe zatuluka. Ndizoletsedwa kusakaniza ndi kunyamula ndi oxidizer ndi mankhwala odyedwa. Chitoliro chotulutsa mpweya chagalimoto yonyamula katundu chiyenera kukhala ndi choletsa moto. Pamene magalimoto akasinja amagwiritsidwa ntchito poyendetsa, maunyolo apansi ayenera kuikidwa. Pofuna kuchepetsa magetsi osasunthika omwe amapangidwa ndi kugwedezeka, ndizotheka kukhazikitsa zogawa mabowo mu thanki. Ndizoletsedwa kukweza kapena kutsitsa zida zamakina ndi zida zomwe zimatha kuphulika. M'chilimwe m'mawa ndi madzulo zoyendera ndi zabwino, muzoyendetsa, kuteteza dzuwa ndi mvula ndi kutentha kwakukulu. Khalani kutali ndi gwero la moto, gwero la kutentha ndi malo otentha kwambiri panthawi yoyimitsa. Mayendedwe amsewu akuyenera kuchitika motsatira njira zomwe zakhazikitsidwa, ndipo zisayime m'malo okhala ndi malo okhala ndi anthu ambiri. Mayendedwe a njanji ndi oletsedwa ku skidding. Kunyamula katundu wambiri ndi zombo zamatabwa kapena za simenti ndizoletsedwa. Zizindikiro ndi zidziwitso zowopsa zidzayikidwa pamayendedwe malinga ndi zofunikira zamayendedwe.

Zizindikiro zakuthupi ndi zamankhwala (%).

Zindikirani: Zogulitsa zimatha kupangidwa ndikuyikidwa molingana ndi zomwe ogwiritsa ntchito akufuna.
