ILanthanum (la) oxide
Lanthanum oxide, eyaziwa nangokuthi umthombo wokungazinzile we-lanthanum ozinzile kakhulu, iyingxenye ye-inorganic equkethe i-rare Endment Lanthanum ne-oksijini. Ilungele izinhlelo zengilazi, i-optic ne-ceramic, futhi isetshenziswe kwezinye izinto ze-ferroeelectric, futhi iyisiphepho sama-catalysts athile, phakathi kokunye ukusetshenziswa.

I-Lanthanum Carbonate
I-Lanthanum CarbonateUsawoti owakhiwa yi-lanthanum (III) Amazwe nama-anions e-carbonate ngefomula yamakhemikhali La2 (CO3) 3. ILanthanum Carbonate isetshenziswa njengezinto zokuqala eLanthanum Chemistry, ikakhulukazi ekwakhekeni okoxide ahlanganisiwe.

Lanthanum (III) Chloride
I-Lanthanum (III) I-Chloride ShiptaHydrate ingumthombo omuhle kakhulu wamanzi we-Sluble Crystalline Lanthanum Lanthanum, okuyikhompiyutha ye-Inorganic ngeFomula Lacl3. Kungusawoti ojwayelekile weLanthanum okusetshenziswa ikakhulukazi ocwaningweni nasekuhambisaneni ngama-chlorides. Kuqinile okumhlophe okuncibilikayo kakhulu emanzini notshwala.

Lanthanum hydroxide
Lanthanum hydroxideIngabe umthombo wamanzi we-insoluble we-insoluble Crystalline Lanthanum, ongatholakala ngokungeza i-alkali efana ne-ammonia ezixazululweni zamanzi ezinosawoti kaLanthanum onjengeLanthanum Nitrate. Lokhu kukhiqiza i-gel-efana ne-gel-efana naleyo ozomiswa emoyeni. ILanthanum Hydroxide ayisebenzi kakhulu ngezinto ze-alkaline, noma kunjalo incibilika kancane kwikhambi le-acid. Isetshenziswa ngokungananazi ngezimo eziphakeme (eziyisisekelo) ph.

Lanthanum hexaboride
Lanthanum hexaboride (ILab6,Ibizwa nangokuthi iLanthanum Boride neLab) iyi-inorganic yamakhemikhali, i-boride yeLanthanum. Njengoba izinto zobumba ze-ceramic ezinobuqili ezinamaphuzu ancibilikayo ka-2210 ° C, iLanthanum Boride i-infoluble kakhulu emanzini ne-hydrochloric acid, futhi iguqukela kwi-oxide lapho kufudunyezwa (kukhale). Amasampula ama-Stoichiometric anemibala eluhlaza okwesibhakabhaka - i-violet ejulile, kanti uBoron-rich (ngenhla lab6.07) aluhlaza okwesibhakabhaka.Lanthanum hexaboride(Lab6) kwaziwa ngobulukhuni bawo, amandla emishini, ukuphuma kwe-thermionic, kanye nezindawo ezinamandla ze-plasmonic. Muva nje, kwasungulwa inqubo entsha yokulinganisa eliphakathi nendawo yenzelwe ukuvumelanisa ngokuqondile lab6 nanoparticles.
