  • Lanthanum(La)Oxide

    Lanthanum(La)Oxide

    Lanthanum Oxide, e mohiotia ana ano he puna Lanthanum tino waiariki, he puhui parakore kei roto te huānga whenua onge te lanthanum me te hāora. He pai mo te karaehe, optic me te raima, ka whakamahia ki etahi rauemi ferroelectric, a he kai whangai mo etahi whakakorikori, me etahi atu whakamahinga.

  • Lanthanum Carbonate

    Lanthanum Carbonate

    Lanthanum Carbonatehe tote i hanga e te lanthanum(III) cation me te anion warowaiha me te tauira matū La2(CO3)3. Ka whakamahia te warowaiwa o Lanthanum hei mea timatanga i roto i te matū lanthanum, ina koa ki te hanga waikura whakauru.

  • Lanthanum(III) Chloride

    Lanthanum(III) Chloride

    Ko te Lanthanum(III) Chloride Heptahydrate he puna wairewa wairewa Lanthanum tioata, he puhui parakore me te tauira LaCl3. He tote noa o te lanthanum e whakamahia ana i roto i te rangahau me te hototahi ki nga hauota. He totoka ma e tino memeha ana ki te wai me te waipiro.

  • Lanthanum Hydroxide

    Lanthanum Hydroxide

    Lanthanum Hydroxidehe puna Lanthanum tioata e kore e rewa i te wai, ka taea te tiki ma te taapiri i te kawakore penei i te haukini ki nga wairewa wai o nga tote lanthanum penei i te lanthanum nitrate. Ka puta mai he rewharewha rite ki te ra ka taea te whakamaroke ki te hau. Ko te Lanthanum hydroxide e kore e nui te hohenga ki nga matū kawakore, engari he paku memeha ki te wairewa waikawa. Ka whakamahia kia hototahi ki nga taiao pH teitei ake (taketake).

  • Lanthanum Hexaboride

    Lanthanum Hexaboride

    Lanthanum Hexaboride (LaB6,ka kiia hoki ko lanthanum boride me LaB) he matū pararopi, he boride o te lanthanum. I te mea he mea whakakorikori he 2210 °C te rewa o te Lanthanum Boride i roto i te wai me te waikawa maatawai, ka huri ki te waikura ina whakamahana (he toka). Ko nga tauira Stoichiometric he papura-puru-puru te tae, engari he kikorangi nga tauira whai-boron (kei runga ake i te LaB6.07).Lanthanum Hexaboride(LaB6) e mohiotia ana mo tona pakeke, te kaha miihini, te tukunga werawera, me nga taonga plasmonic kaha. Ina tata nei, i hangaia he tikanga waihanga hou-mahana-mahana hei whakahiato tika i nga matūriki nano LaB6.
