ExploringtheWorldofRareEarthElements

TheImportanceofRareEarthElements

Rareearthelements(REEs)areagroupof17metallicelementswithuniquechemicalandphysicalproperties,suchashighmagnetism,luminescence,andelectricalconductivity.Theseelementsareusedinawiderangeofapplications,fromsmartphonesandrenewableenergytechnologiestomedicalequipmentandmilitaryweaponry.Asaresult,thedemandforREEshasbeenincreasingrapidlyinrecentyears.ChinacurrentlydominatestheglobalproductionandsupplyofREEs,leadingtoconcernsoveritsstrategicimportanceandpotentialfordisruption.DevelopingalternativesourcesofREEshasbecomeamajorpriorityformanycountriesaroundtheworld.
