  • Scandium oxide

    Scandium oxide

    Scandium(III) Oxide kapena scandia ndi organic pawiri ndi formula Sc2O3. Maonekedwe ndi ufa woyera wa ufa wa cubic system. Ili ndi mawu osiyanasiyana monga scandium trioxide, scandium(III) oxide ndi scandium sesquioxide. Makhalidwe ake a physico-chemical ali pafupi kwambiri ndi ma oxide ena osowa padziko lapansi monga La2O3, Y2O3 ndi Lu2O3. Ndi imodzi mwa ma oxide angapo a zinthu zapadziko lapansi osowa kwambiri okhala ndi malo osungunuka kwambiri. Kutengera ukadaulo wapano, Sc2O3/TREO ikhoza kukhala 99.999% yapamwamba kwambiri. Imasungunuka mu asidi otentha, koma osasungunuka m'madzi.
