Holmium Oxide
Holmium (III) oxide, los yogholmium oxideNws yog ib qho insoluble thermally ruaj khov Holmium qhov chaw. Nws yog ib qho tshuaj sib xyaw ntawm lub ntiaj teb tsis tshua muaj holmium thiab oxygen nrog cov mis Ho2O3. Holmium oxide tshwm sim nyob rau hauv me me nyob rau hauv cov minerals monazite, gadolinite, thiab lwm yam minerals tsawg-lub ntiaj teb. Holmium hlau yooj yim oxidizes hauv huab cua; Yog li ntawd, muaj holmium nyob rau hauv cov xwm yog synonymous nrog hais tias ntawm holmium oxide. Nws yog tsim rau iav, optic thiab ceramic daim ntaub ntawv.
