ʻOkika Scandium
ʻO Scandium(III) Oxide a i ʻole scandia he hui inorganic me ke ʻano Sc2O3. ʻO ke ʻano he pauka keʻokeʻo maikaʻi o ka ʻōnaehana cubic. Loaʻa iā ia nā ʻano like ʻole e like me scandium trioxide, scandium(III) oxide a me scandium sesquioxide. Ua kokoke loa kona mau waiwai physico-chemical i nā oxides honua kakaʻikahi ʻē aʻe e like me La2O3, Y2O3 a me Lu2O3. ʻO ia kekahi o nā oxides o nā mea honua kakaʻikahi me kahi kiko heheʻe kiʻekiʻe. Ma muli o ka ʻenehana o kēia manawa, hiki i ka Sc2O3/TREO ke 99.999% ma ke kiʻekiʻe loa. Hiki ke hoʻoheheʻe ʻia i ka waikawa wela, akā naʻe, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai.
