Matsenga osowa kwambiri padziko lapansi: Lanthanum Theide

Lanthanum oxide,mawonekedwe a matopeLa2o3, ma curcar olemera 325.8091. Makamaka amagwiritsidwa ntchito popanga galasi lowoneka bwino komanso ulusi wamaso.

Katundu wa mankhwala

Kusungunuka pang'ono m'madzi ndikusungunuka mosavuta mu acid kuti apange mchere wofanana.

Kuwonetsedwa mlengalenga, ndikosavuta kuyamwa kaboni dayokisi ndi madzi, pang'onopang'ono kutembenukira ku Lanthanum Carbonate.

KuwotchaLanthanum oxideimaphatikiza ndi madzi kuti amasule kutentha kwambiri.

katundu wakuthupi

Mawonekedwe ndi malo: oyera oyera.

Kachulukidwe: 6.51 g / ml pa 25 ° C

Malo osungunuka: 2315 ° C, owiritsa: 4200 ° C

Kusungunuka: kusungunuka mu acids ndi ammonium chloride, zopanda mafuta m'madzi ndi ma ketoni.

Njira yopanga

1. Zopangira zowonjezera za njira yochotserare ndi dziko lapansi lopanda tanthauzo pambuyo pochotsa cerium kuchotsedwa kwa 50%, trace kuchuluka kwa cepo2, ndi 30% 1O3. Kuphatikizidwa kukhala Σ osowa kwambiri padziko lapansi ndi kuchuluka kwa 320-330g / l wa photoyl heptyl atchentphonine (P350), mu P350 Kerosen System 3-38. Njira yotsalira yomwe ili ndi Lanthanum idasalowerera ndi ammonia, yokhazikika ndi oyalilic acid Kuchotsedwa ku Lantanum Phusphate Cermate kapena wokonzedwa ndi kuwotcha lanthenum carbonate kapena nitrate. Itha kupezekanso mwa kutentha ndi kuwola kwa oxanum of Lanthanum.

2. Ikani la (oh) 3 mu platinam wopaka, wowuma pa 200 ℃, woyaka pa 500 ℃, ndikuwola ma 840 ℃ kuti mupeze lanthanum oxide.

Karata yanchito

Makamaka amagwiritsidwa ntchito popanga galasi lowoneka bwino komanso ulusi wamaso. Amagwiritsidwanso ntchito pamagetsi amagetsi ngati diaractic capactors ndi piezoelect zowonjezera zowonjezera. Amagwiritsidwanso ntchito ngati zopangira zopangira la lanzanum komanso ngati chothandizira kupatukana ndi kuyeretsa.

Gawo lofunsidwa: Makamaka zopangira galasi lazikulu, bolodi yolimba kwambiri ya fibern, yoyenerera kupanga makamera, makamera, microscoscophkostolo, ndi ntchito zapamwamba za zida zowoneka bwino. Amagwiritsidwanso ntchito popanga capactors a ceramic, piezoelectric ceralant, ndi x-ray luminecent zinthu mongaLanthanum bromiderufa. Kuchokera ku Lantanum Phusphate cerete kapena kupezeka ndi kuwotcha carbonate kapena nitrate. Itha kupezekanso mwa kutentha ndi kuwola kwa oxanum of Lanthanum. Zogwiritsidwa ntchito ngati chothandizira pamachitidwe osiyanasiyana, monga makokotala a catalytic a monoxium akapota ndi cadmium oxide, komanso mankhwala hydrogenation ya carbon ponoxide atanyamula palladium. Lanthanum oxide kulowetsedwa ndi lithiam oxide kapena zirconia (1%) akhoza kugwiritsidwa ntchito popanga maginito a Ferrit. Ndi chothandizira chothandiza kwambiri pakuphatikizira kwa methane kuti mupange ethane ndi ethylene. Amagwiritsidwa ntchito kukonza kutengera kutentha kwa kutentha ndi ma serium cananate (attio3) ndi strantio3) ferroectrics, komanso magalasi owala.
