  • Lanthanum(La)Oxide

    Lanthanum(La)Oxide

    Lanthanum Oxide, ʻike ʻia hoʻi ma ke ʻano he kumu Lanthanum paʻa ʻole hiki ke hoʻoheheʻe ʻia, he pūhui inorganic i loaʻa ka lanthanum me ka oxygen. He kūpono ia no nā aniani, optic a me nā noi seramika, a hoʻohana ʻia i kekahi mau mea ferroelectric, a he mea hānai no kekahi mau catalysts, i waena o nā hoʻohana ʻē aʻe.

  • Lanthanum Carbonate

    Lanthanum Carbonate

    Lanthanum Carbonatehe paʻakai i hana ʻia e nā ʻona lanthanum(III) a me nā anion carbonate me ke ʻano kemika La2(CO3)3. Hoʻohana ʻia ka Lanthanum carbonate ma ke ʻano he mea hoʻomaka i ka kemika lanthanum, ʻoi aku ka nui o ka hana ʻana i nā oxides hui ʻia.

  • Lanthanum(III) Chloride

    Lanthanum(III) Chloride

    ʻO Lanthanum(III) Chloride Heptahydrate kahi punawai Lanthanum crystalline hiki ke hoʻoheheʻe ʻia i ka wai maikaʻi loa, ʻo ia ka pūhui inorganic me ke ʻano LaCl3. He paʻakai maʻamau ia o ka lanthanum i hoʻohana nui ʻia i ka noiʻi a kūpono me nā chlorides. He paʻa keʻokeʻo ia i hiki ke hoʻoheheʻe ʻia i ka wai a me ka waiʻona.

  • Lanthanum Hydroxide

    Lanthanum Hydroxide

    Lanthanum HydroxideHe puna wai Lanthanum hiki ʻole ke hoʻoheheʻe ʻia i ka wai, hiki ke loaʻa ma ka hoʻohui ʻana i kahi alkali e like me ka amonia i nā wai wai o nā paʻakai lanthanum e like me ka lanthanum nitrate. Hoʻopuka kēia i ka gel-like precipitate a laila hiki ke hoʻomaloʻo ʻia i ka ea. ʻAʻole hana nui ʻo Lanthanum hydroxide me nā mea alkaline, akā hiki ke hoʻoheheʻe iki ʻia i loko o ka hopena ʻakika. Hoʻohana like ʻia me nā kaiapuni pH kiʻekiʻe (kumu).

  • Lanthanum Hexaboride

    Lanthanum Hexaboride

    Lanthanum Hexaboride (LaB6,kapa ʻia hoʻi ka lanthanum boride a me LaB) he mea ʻano kemika, he boride o ka lanthanum. E like me refractory ceramic mea i loaʻa kahi heheʻe o 2210 °C, Lanthanum Boride mea loa insoluble i ka wai a me ka hydrochloric waika, a hoohuli i ka oxide ke wela (calcined). ʻO nā laʻana Stoichiometric i waihoʻoluʻu i ka poni-violet, aʻo nā mea waiwai boron (ma luna o LaB6.07) he uliuli.Lanthanum Hexaboride(LaB6) ʻike ʻia no kona paʻakikī, ikaika mechanical, thermionic emission, a me nā waiwai plasmonic ikaika. I kēia mau lā, ua hoʻomohala ʻia kahi ʻenehana synthetic hou no ka hoʻopili pololei ʻana i nā nanoparticles LaB6.
