    Europium(III) Oxide

    Europium(III) Oxide (Eu2O3)he hui kemika o ka europium a me ka oxygen. He mau inoa ʻē aʻe ka Europium oxide e like me Europia, Europium trioxide. He ʻulaʻula keʻokeʻo keʻokeʻo ʻo Europium oxide. ʻElua mau hanana like ʻole o ka Europium oxide: cubic a me monoclinic. Ua aneane like ka cubic structured europium oxide me ka magnesium oxide structure. ʻAʻole hiki ke hoʻoheheʻe ʻia ka Europium oxide i ka wai, akā hiki ke hoʻoheheʻe ʻia i loko o nā ʻakika mineral. He mea paʻa wela ka Europium oxide me ka helu heheʻe ma 2350 oC. ʻO ka Europium oxide ka waiwai nui e like me ka magnetic, optical a me ka luminescence waiwai i mea nui i kēia mea. Hiki i ka Europium oxide ke komo i ka makū a me ka carbon dioxide i ka lewa.
