Lanthanum Hydrooxide
Lanthanum Hydrooxideimvura yakanyanyisa isingasviki crystalline Lanthanum source, iyo inogona kuwanikwa nekuwedzera alkali yakadai seammonia kune aqueous solutions yelanthanum salts se lanthanum nitrate. Izvi zvinogadzira gel-semvura inonaya iyo inogona kuomeswa mumhepo. Lanthanum hydroxide haibatike zvakanyanya nealkaline zvinhu, asi inonyungudika zvishoma muine acidic solution. Inoshandiswa zvinoenderana nepamusoro (yakakosha) pH nharaunda.

Lanthanum Hexaboride
Lanthanum Hexaboride (LaB6,inonziwo lanthanum boride uye LaB) ikemikari inorganic, boride ye lanthanum. Sezvinoita refractory ceramic material ine nzvimbo yakanyunguduka ye2210 °C, Lanthanum Boride hainyanyi kunyungudika mumvura uye hydrochloric acid, uye inoshandura kuita oxide kana yapiswa (calcined). Stoichiometric samples dzine ruvara rwepepuru-violet, nepo boron-rich (pamusoro peLaB6.07) ibhuruu.Lanthanum Hexaboride(LaB6) inozivikanwa nekuoma kwayo, simba remagetsi, thermionic emission, uye yakasimba plasmonic zvinhu. Munguva pfupi yapfuura, imwe nyowani yepakati-tembiricha yekugadzira tekinoroji yakagadziridzwa kuti igadzirise zvakananga LaB6 nanoparticles.
