  • I-Holmium oxide

    I-Holmium oxide

    I-Holmium(III) oxide, nomai-holmium oxideiwumthombo weHolmium ongancibiliki kakhulu. Kuyinhlanganisela yekhemikhali ye-elementi eyivelakancane ye-holmium ne-oksijini enefomula ethi Ho2O3. I-Holmium oxide yenzeka ngamanani amancane kumaminerali i-monazite, i-gadolinite, nakwamanye amaminerali angavamile. I-Holmium metal i-oxidizes kalula emoyeni; ngakho-ke ukuba khona kwe-holmium emvelweni kufana nalokho kwe-holmium oxide. Ilungele ukusetshenziswa kwengilazi, i-optic kanye ne-ceramic.
