  • Lanthanum(La)Oxide

    Lanthanum(La)Oxide

    Lanthanum oxide, yomwe imadziwikanso kuti gwero la Lanthanum yosasunthika kwambiri, ndi gwero lachilengedwe lomwe lili ndi rare Earth element lanthanum ndi oxygen. Ndi yoyenera kuyika magalasi, optic ndi ceramic, ndipo imagwiritsidwa ntchito muzinthu zina za ferroelectric, ndipo ndi chakudya chazothandizira zina, pakati pa ntchito zina.

  • Lanthanum carbonate

    Lanthanum carbonate

    Lanthanum carbonatendi mchere wopangidwa ndi lanthanum(III) cations ndi carbonate anions ndi mankhwala chilinganizo La2(CO3)3. Lanthanum carbonate imagwiritsidwa ntchito ngati poyambira mu chemistry ya lanthanum, makamaka popanga ma oxide osakanikirana.

  • Lanthanum(III) Chloride

    Lanthanum(III) Chloride

    Lanthanum(III) Chloride Heptahydrate ndi madzi sungunuka crystalline Lanthanum gwero, amene ali pawiri zosakhala ndi chilinganizo LaCl3. Ndi mchere wamba wa lanthanum womwe umagwiritsidwa ntchito makamaka pofufuza komanso umagwirizana ndi ma chlorides. Ndi cholimba choyera chomwe chimasungunuka kwambiri m'madzi ndi mowa.

  • Lanthanum Hydrooxide

    Lanthanum Hydrooxide

    Lanthanum Hydrooxidendi gwero lamadzi osasungunuka la crystalline Lanthanum, lomwe lingapezeke powonjezera alkali monga ammonia ku njira zamadzimadzi za mchere wa lanthanum monga lanthanum nitrate. Izi zimapanga mpweya wofanana ndi gel womwe ukhoza kuwumitsidwa mumlengalenga. Lanthanum hydroxide sichita zambiri ndi zinthu zamchere, komabe imasungunuka pang'ono mu acidic solution. Amagwiritsidwa ntchito mogwirizana ndi malo apamwamba (oyambira) pH.

  • Lanthanum Hexaboride

    Lanthanum Hexaboride

    Lanthanum Hexaboride (LaB6,Amatchedwanso lanthanum boride ndi LaB) ndi mankhwala osakhazikika, a boride a lanthanum. Monga refractory ceramic material yomwe ili ndi malo osungunuka a 2210 ° C, Lanthanum Boride imasungunuka kwambiri m'madzi ndi hydrochloric acid, ndipo imasandulika ku oxide ikatenthedwa (calcined). Zitsanzo za Stoichiometric ndi zamitundu yofiirira-violet, pomwe zolemera za boron (pamwamba pa LaB6.07) ndi zabuluu.Lanthanum Hexaboride(LaB6) imadziwika chifukwa cha kuuma kwake, mphamvu zamakina, kutulutsa kwa thermionic, komanso mphamvu za plasmonic. Posachedwapa, njira yatsopano yopangira kutentha kwapakatikati idapangidwa kuti ipangitse mwachindunji ma nanoparticles a LaB6.
