Lutetium (III) Oxide(Lu2O3), yomwe imadziwikanso kuti lutecia, ndi yolimba yoyera komanso yamtundu wa lutetium. Ndi gwero la Lutetium losasungunuka kwambiri, lomwe lili ndi mawonekedwe a kristalo wa cubic ndipo limapezeka mu mawonekedwe a ufa woyera. Osayidi wazitsulo wapadziko lapansi wosowa kwambiriyu amawonetsa zinthu zabwino zakuthupi, monga malo osungunuka kwambiri (pafupifupi 2400 ° C), kukhazikika kwa gawo, mphamvu zamakina, kuuma, kukhathamiritsa kwamafuta, komanso kukulitsa kwamafuta ochepa. Ndizoyenera magalasi apadera, optic ndi ceramic application. Amagwiritsidwanso ntchito ngati zofunikira zopangira ma kristalo a laser.
