Lanthanum Hexaboride
Lanthanum Hexaboride (LaB6,ʻo ia hoʻi ka lanthanum boride a me LaB) he kemika inorganic, he boride o ka lanthanum. Ma ke ʻano he mea keramika refractory nona ka pae heheʻe o 2210 °C, ʻaʻole hiki ke hoʻoheheʻe ʻia ʻo Lanthanum Boride i ka wai a me ka waikawa hydrochloric, a hoʻololi i ka oxide i ka wā e hoʻomehana ʻia ai (calcined). Hoʻoluʻu ʻia nā laʻana Stoichiometric i ka poni-violet ikaika, ʻoiai ʻo nā mea waiwai boron (ma luna o LaB6.07) he uliuli.Lanthanum Hexaboride(LaB6) ua kaulana no kona paʻakikī, ka ikaika mechanical, ka hoʻokuʻu thermionic, a me nā waiwai plasmonic ikaika. I kēia manawa, ua hoʻomohala ʻia kahi ʻenehana synthetic mahana-waena hou e synthesize pololei i nā nanoparticles LaB6.

Lanthanum(La)Oxide
ʻOkika Lanthanum, i ʻike ʻia hoʻi he kumu Lanthanum paʻa wela insoluble kiʻekiʻe, he hui inorganic ia e loaʻa ana ka lanthanum honua laha ʻole a me ka oxygen. He kūpono ia no nā noi aniani, optic a me ka seramika, a hoʻohana ʻia i kekahi mau mea ferroelectric, a he feedstock no kekahi mau catalysts, ma waena o nā hoʻohana ʻē aʻe.

Lanthanum Hydroxide
Lanthanum Hydroxidehe kumu Lanthanum crystalline hiki ʻole ke hoʻoheheʻe ʻia i ka wai, hiki ke loaʻa ma ka hoʻohui ʻana i kahi alkali e like me ka ammonia i nā hopena wai o nā paʻakai lanthanum e like me ka lanthanum nitrate. Hoʻopuka kēia i kahi precipitate e like me ka gel a laila hiki ke hoʻomaloʻo ʻia i ka lewa. ʻAʻole pane nui ka Lanthanum hydroxide me nā mea alkaline, akā naʻe he mea hoʻoheheʻe iki ia i ka hopena acidic. Hoʻohana ʻia ia me nā ʻano pH kiʻekiʻe (kumu).
