ILanthanum(La)Oxide
I-Lanthanum oxide, ekwaziwa ngokuba ngumthombo weLanthanum ongenakunyibilika kakhulu we-thermal, yi-inorganic compound equkethe i-rare element yomhlaba i-lanthanum kunye ne-oxygen.Ifanelekile kwiglasi, i-optic kunye ne-ceramic applications, kwaye isetyenziswe kwezinye izinto ze-ferroelectric, kwaye iyindawo yokutya ye-catalysts ethile, phakathi kwezinye izinto.

ILanthanum Hydroxide
ILanthanum Hydroxidengumthombo wecrystalline weLanthanum onganyibilikiyo wamanzi, onokufumaneka ngokudibanisa ialkali efana neammonia kwizisombululo ezimanzi zetyuwa zelanthanum ezifana nelanthanum nitrate.Oku kuvelisa ijeli efana nemvula enokomiswa emoyeni.ILanthanum hydroxide ayichaphazeli kakhulu kwizinto zealkaline, nangona kunjalo inyibilika kancinane kwisisombululo esineasidi.Isetyenziswa ngokuhambelanayo neendawo eziphezulu (ezisisiseko) ze-pH.

Lanthanum Hexaboride
Lanthanum Hexaboride (ILaB6,ikwabizwa ngokuba yi-lanthanum boride kunye ne-LaB) yikhemikhali ye-inorganic, i-boride ye-lanthanum.Njengempahla ye-ceramic ephikisayo enendawo yokunyibilika ye-2210 ° C, iLanthanum Boride ayinakunyibilika kakhulu emanzini kunye ne-hydrochloric acid, kwaye iguqulela kwi-oxide xa ishushu (i-calcined).Iisampuli ze-Stoichiometric zinemibala ebomvu-violet, ngelixa i-boron-rich rich (ngaphezulu kwe-LaB6.07) iluhlaza okwesibhakabhaka.Lanthanum Hexaboride(LaB6) iyaziwa ngokuba lukhuni kwayo, amandla omatshini, ukukhutshwa kwe-thermionic, kunye neempawu ezinamandla ze-plasmonic.Kutshanje, kuphuhliswe indlela entsha yokwenziwa kobushushu obuphakathi ukuze idibanise ngqo iLaB6 nanoparticles.
