Waa maxayHolmium oxideloo isticmaalo?
Holmium oxidewaa mid ka mid ah midabada loo isticmaalo zirconia cubic iyo galaas, sida halbeegga cabbirka ee spectrophotometers indhaha, sida kicinta khaaska ah, fosfoor iyo walxo laser ah, oo bixiya midab huruud ah ama casaan. Waxa loo isticmaalaa samaynta muraayadaha midabka gaarka ah. Muraayadaha ka kooban holmium oxide iyo xalalka holmium oxide waxay leeyihiin taxane nuugista indhaha oo fiiqan oo kala duwan oo muuqda. Sida inta badan oksaydhyada kale ee walxaha naadirka ah ee dhulka, holmium oxide waxa loo istcimaalaa kiciya khaas ah, fosfoor iyo walxo laysarka ah. Laser Holmium wuxuu ku shaqeeyaa mowjadda dhererka qiyaastii 2.08 micromitir, ha ahaato mid garaaca ama nidaam joogto ah. Laysarkani waa badbaado indhaha waxaana loo isticmaalaa daawada, daboolka, cabbiraadaha xawaaraha dabaysha iyo la socodka jawiga. Holmium waxa uu nuugi karaa neutrons-ka fission-bred, waxa kale oo loo isticmaalaa reactors nukliyeerka si ay uga ilaaliso falcelinta silsiladda atomiga in ay ka baxdo xakamaynta.
