    Lutetium (III) Oxide

    Lutetium (III) Oxide(Lu2O3), tseem hu ua lutecia, yog cov khoom dawb thiab lub cubic compound ntawm lutetium.Nws yog ib qho tsis zoo thermally ruaj khov Lutetium qhov chaw, uas muaj cov qauv siv lead ua cubic thiab muaj nyob rau hauv cov hmoov dawb.Lub ntiaj teb no tsis tshua muaj hlau oxide nthuav tawm cov khoom zoo ntawm lub cev, xws li lub siab melting point (nyob ib ncig ntawm 2400 ° C), theem stability, mechanical zog, hardness, thermal conductivity, thiab thermal expansion.Nws yog tsim rau tshwj xeeb tsom iav, optic thiab ceramic daim ntaub ntawv.Nws kuj tseem siv los ua cov ntaub ntawv tseem ceeb rau laser muaju.
