Lanthanum oxide (yomwe imadziwikanso kuti lanthana) ndi mankhwala omwe ali ndi formula La2O3. Ndiwosowa padziko lapansi okusayidi ndi zoyera zolimba zokhala ndi mawonekedwe a cubic crystal. Lanthanum oxide ndi chinthu chotenthetsera kwambiri ndipo chimagwiritsidwa ntchito m'njira zosiyanasiyana chifukwa cha kukhazikika kwake kwamankhwala komanso kukana dzimbiri. Amagwiritsidwa ntchito ngati zinthu zopangira ma phosphors kuti agwiritsidwe ntchito mu machubu a cathode ray ndi nyali za fulorosenti, ngati dopant mu zida za semiconductor, komanso ngati chothandizira. Amagwiritsidwanso ntchito popanga zitsulo zadothi komanso ngati tracer mu kafukufuku wa zamoyo ndi mankhwala.

Kugwiritsa ntchito

Lanthanum Oxide, yomwe imatchedwanso Lanthana, yoyera kwambiri ya Lanthanum Oxide (99.99% mpaka 99.999%) imagwiritsidwa ntchito popanga magalasi apadera opangira magalasi kuti magalasi asasunthike bwino, ndipo amagwiritsidwa ntchito mu La-Ce-Tb phosphors pa nyali za fulorosenti ndikupanga kuwala kwapadera. magalasi, monga magalasi a infrared-absorbent, komanso magalasi a kamera ndi telescope, Low grade Lanthanum Oxide amagwiritsidwa ntchito kwambiri mu ceramics ndi FCC catalyst, komanso ngati zipangizo zopangira Lanthanum Metal; Lanthanum okosijeni amagwiritsidwanso ntchito ngati mbewu kukula zowonjezera pa madzi gawo sintering wa Silicon Nitride ndi Zirconium Diboride.

Dziko lapansi losowa kwambiri lanthanum oxide la2o3
