Ndi chiyaniHolmium oxidekugwiritsidwa ntchito?
Holmium oxideis one of the colorants used for cubic zirconia and glass, as a calibration standard for optical spectrophotometers, as a specialty catalyst, phosphor and a laser material, providing yellow or red coloring. Amagwiritsidwa ntchito popanga magalasi achikuda apadera. Magalasi okhala ndi holmium oxide ndi holmium oxide solution ali ndi nsonga zakuthwa zakuthwa zakuthwa pamawonekedwe owoneka bwino. Monga ma oxide ena ambiri azinthu zosowa zapadziko lapansi, holmium oxide imagwiritsidwa ntchito ngati chothandizira chapadera, phosphor ndi zida za laser. Laser ya Holmium imagwira ntchito pamtunda wa pafupifupi 2.08 micrometres, kaya ndi pulsed kapena mosalekeza. Laser iyi ndi yotetezeka m'maso ndipo imagwiritsidwa ntchito ngati mankhwala, ma lidar, kuyeza kwa liwiro la mphepo komanso kuyang'anira mlengalenga. Holmium imatha kuyamwa ma neutroni opangidwa ndi fission, imagwiritsidwanso ntchito m'manyutroni a nyukiliya kuti ma atomiki asamayende bwino.
