Dab tsi yogHolmium Oxidesiv rau?
Holmium oxideyog ib qho ntawm cov xim siv rau cubic zirconia thiab iav, raws li tus qauv calibration rau optical spectrophotometers, raws li ib tug tshwj xeeb catalyst, phosphor thiab ib tug laser khoom, muab daj los yog liab xim. Nws yog siv los ua cov tsom iav tshwj xeeb. Cov iav uas muaj holmium oxide thiab holmium oxide cov kev daws teeb meem muaj ntau qhov kev nqus qhov muag pom tseeb hauv qhov pom spectral ntau. Raws li feem ntau lwm cov oxides ntawm lub ntiaj teb tsis tshua muaj, holmium oxide yog siv los ua ib qho tshwj xeeb catalyst, phosphor thiab laser khoom. Holmium laser ua haujlwm ntawm wavelength ntawm li 2.08 micrometers, txawm tias nyob rau hauv kev sib hloov los yog tsis tu ncua. Lub laser no yog qhov muag zoo thiab yog siv rau hauv cov tshuaj, lidars, ntsuas cua tshaj tawm thiab kev saib xyuas huab cua. Holmium tuaj yeem nqus cov fission-bred neutrons, nws kuj tseem siv rau hauv cov reactors nuclear kom atomic chain reaction los ntawm kev tswj tsis tau.
