Lanthhanum (LA) Oxide
Lanthhanum oxide, tseem hu ua qhov tsis muaj insoluble kub ruaj khov Nws yog qhov haum rau iav, optic thiab ceramic thiab siv hauv qee cov ntaub ntawv ferroelrictric, thiab yog ib lub pub rau cov neeg siv khoom, ntawm lwm cov siv.
-
Lanthhanum Carbonate
Lanthhanum Carbonateyog ntsev tsim los ntawm lanthhanum (III) cations thiab carbonate actions nrog tshuaj lom neeg LA2 (CO3) 3. Lanthhanum carbonate yog siv los ua cov khoom siv pib hauv kev ua haujlwm hauv kev sib xyaw ua ke oxides.

Lanthhanum (III) Chloride
Lanthhant (III) ceptoride heptahydrate yog ib qho zoo tshaj dej soluble crystalline, uas yog qhov inorganic compound nrog cov mislula lacl3. Nws yog cov ntsev uas nquag muaj cov ntsev ntawm cov lus qhia uas yog siv hauv kev tshawb fawb thiab tshaj chlorides. Nws yog cov tawv dawb uas yog soluble heev hauv dej thiab dej cawv.

Lanthant hydroxide
Lanthant hydroxideYog ib tug dej ntws heev insoluble crystalline crystalline, uas tuaj yeem tau txais los ntawm kev ntxiv cov alkali mus rau cov ntsev uas muaj aquehanum xws li lub suab nitrate. Qhov no tsim cov gel-zoo li nag lossis nag los uas tuaj yeem qhuav hauv huab cua. Lanthhana hydroxide tsis raug tshuaj ntau nrog cov tshuaj Alkaline, txawm li cas los yog soluble me ntsis hauv cov kua qaub. Nws yog siv ua ke nrog ntau dua (theem pib) pH.

Lanthhanum Hexaboride
Lanthhanum Hexaboride (Lab66,Kuj tseem hu ua Lanthhanum boride thiab lab) yog ib qho kev ua tsis tau zoo nkauj, ib qho kev sib tsoo ntawm Lanthhant. Raws li refractory tej hub khoom uas muaj lub ntsiab lus melting ntawm 2210 ° C, Lanthhanum buride yog hyprochloric acid, thiab hloov mus rau oxide thaum rhuab (calcined). Stoichiometric kuaj yog xim khaus khaus-violet, thaum cov neeg muaj txiaj ntsig ntawm cov neeg nplua nuj (Lab Lab6.07) yog xiav.Lanthhanum Hexaboride(Lab6) paub txog nws hardness, tshuab siv zog, kev tawm tswv yim cuam tshuam, thiab muaj zog plasmonic khoom. Tsis ntev los no, ib qho txheej txheem tshiab-hluav taws xob kub tau tsim los ua ncaj qha synthesize Luar6 nanoparticles.
