I-Lanthanum(La)Oxide
I-Lanthanum oxide, owaziwa nangokuthi umthombo we-Lanthanum ozinze ngokushisa kakhulu ongancibiliki, iyinhlanganisela yezinto ezingaphili equkethe i-elementi yomhlaba engavamile i-lanthanum nomoya-mpilo. Ilungele ukusetshenziswa kwengilazi, i-optic kanye ne-ceramic, futhi isetshenziswa kwezinye izinto ze-ferroelectric, futhi iwukudla kokuphakelayo kwama-catalyst athile, phakathi kokunye ukusetshenziswa.

I-Lanthanum carbonate
I-Lanthanum carbonateusawoti owenziwe i-lanthanum(III) cations kanye ne-carbonate anions ne-chemical formula La2(CO3)3. I-Lanthanum carbonate isetshenziswa njengesiqalo kukhemikhali ye-lanthanum, ikakhulukazi ekwakheni ama-oxide axubile.

I-Lanthanum(III) Chloride
I-Lanthanum(III) Chloride Heptahydrate iwumthombo we-Lanthanum oncibilikayo emanzini, okuyinhlanganisela ye-inorganic ene-formula LaCl3. Usawoti ojwayelekile we-lanthanum osetshenziswa kakhulu ocwaningweni futhi ohambisana nama-chloride. Iqinile emhlophe encibilika kakhulu emanzini nasezitshwaleni.

I-Lanthanum Hydroxide
I-Lanthanum Hydroxideiwumthombo we-crystalline we-Lanthanum ongancibiliki kakhulu emanzini, ongatholakala ngokungeza i-alkali efana ne-ammonia ezixazululweni ezinamanzi kasawoti we-lanthanum njenge-lanthanum nitrate. Lokhu kukhiqiza imvula efana nejeli engase yomiswe emoyeni. I-Lanthanum hydroxide ayiphenduli kakhulu ezintweni ezine-alkaline, nokho iyancibilika kancane kusisombululo esine-asidi. Isetshenziswa ngokuhambisana nezindawo eziphezulu (eziyisisekelo) ze-pH.

I-Lanthanum Hexaboride
I-Lanthanum Hexaboride (LaB6,ebizwa nangokuthi i-lanthanum boride kanye ne-LaB) iyikhemikhali ye-inorganic, i-boride ye-lanthanum. Njengempahla ye-ceramic ephikisayo enephuzu lokuncibilika elingu-2210 °C, i-Lanthanum Boride ayincibiliki kakhulu emanzini ne-hydrochloric acid, futhi iguqulela ku-oxide lapho ishiswa (i-calcined). Amasampula e-Stoichiometric anombala onsomi-violet, kuyilapho acebile nge-boron (ngaphezulu kwe-LaB6.07) aluhlaza okwesibhakabhaka.I-Lanthanum Hexaboride(LaB6) yaziwa ngobulukhuni bayo, amandla emishini, ukukhishwa kwe-thermionic, kanye nezakhiwo eziqinile ze-plasmonic. Muva nje, kusungulwe indlela entsha yokwenziwa kwezinga lokushisa elimaphakathi ukuze kuhlanganiswe ngokuqondile ama-nanoparticles e-LaB6.
