  • Lanthanum(La)Oxide

    Lanthanum(La)Oxide

    Lanthanum Oxide, e lauiloa foi o se puna Lanthanum mautu vevela e matua le mafai ona faʻaaogaina, o se mea faʻapipiʻi le faʻaogaina o loʻo iai le elemene lanthanum ma le okesene. E talafeagai mo tioata, optic ma ceramic talosaga, ma faaaoga i nisi mea ferroelectric, ma o se feedstock mo nisi catalysts, faatasi ai ma isi faaaogaina.

  • Lanthanum Carbonate

    Lanthanum Carbonate

    Lanthanum Carbonateo se masima e fausia e le lanthanum(III) cations ma carbonate anion ma le fua fa'a-kemikolo La2(CO3)3. Lanthanum carbonate o lo'o fa'aaogaina e fai ma mea amata ile kemisi lanthanum, aemaise ile fa'atupuina ole oxide fefiloi.

  • Lanthanum(III) Chloride

    Lanthanum(III) Chloride

    Lanthanum(III) Chloride Heptahydrate ose vai e sili ona lelei soluble tioata Lanthanum puna, lea o se tuufaatasiga inorganic ma le fua LaCl3. O se masima masani o le lanthanum lea e masani ona faʻaaogaina i suʻesuʻega ma fetaui ma chlorides. Ose pa'epa'e ma'a e sili ona so'a i le vai ma le 'ava malosi.

  • Lanthanum Hydroxide

    Lanthanum Hydroxide

    Lanthanum Hydroxideo se puna tioata Lanthanum tioata maualuga e le mafai ona fa'afefeteina, lea e mafai ona maua e ala i le fa'aopoopoina o se alkali e pei o le ammonia i vaifofo vai o masima lanthanum e pei o le lanthanum nitrate. Ole mea lea e maua mai ai se pa'u pei o se gel e mafai ona fa'amago ile ea. O le Lanthanum hydroxide e le fa'afefe tele i mea alkaline, peita'i e solu teisi i le vaifofo oona. E fa'aogaina fa'atasi ma siosiomaga maualuga (fa'avae) pH.

  • Lanthanum Hexaboride

    Lanthanum Hexaboride

    Lanthanum Hexaboride (LaB6,e ta'ua fo'i le lanthanum boride ma le LaB) ose vaila'au fa'aletino, o se boride o le lanthanum. I le avea ai ma mea fa'amea fa'a'ala'au e iai le mea fa'afefeteina o le 2210 °C, o le Lanthanum Boride e matua le mafai ona fa'afefe i le vai ma le hydrochloric acid, ma liua i le oxide pe a vevela (calcined). O fa'ata'ita'iga Stoichiometric e lanu viole-violet malosi, ae o fa'amea-boron (i luga a'e o le LaB6.07) e lanumoana.Lanthanum Hexaboride(LaB6) e lauiloa mo lona maaa, malosi faʻainisinia, faʻamalama faʻamalama, ma mea faʻapitoa plasmonic. Talu ai nei, na fa'atupuina ai se faiga fou fa'akomepiuta fou e tu'u sa'o ai LaB6 nanoparticles.
