Introduction

In2002,aresearchteamfromSandiaNationalLaboratories,USA,discoveredanewmineralthatdefiedallexpectations.ThemineralwasfoundintheJackpileMine,whichisauraniumminethatproducesarangeofrareminerals.However,themineralthatwasdiscoveredwasunlikeanyotherfoundatthemine.Afterathoroughanalysis,theresearchersconfirmedthatthemineralwasaperoxidecompoundcomposedofhydrogenperoxide,uranylions,andwatermolecules.Thismineralwasnamedstudtiteinhonorofitsdiscoverer,StephenStudt,amineralcollectorandgeologistfromNewMexico.

PropertiesofStudtite

Studtitehasahighlyspecificchemicalcompositionthatmakesituniqueamongallotherknownminerals.Themineralhasageneralformulaof[(UO2)O2(H2O)2]2(H2O2)3,whichrepresentsacombinationofuranylions,watermolecules,andhydrogenperoxide.Thecrystalstructureofstudtiteisorthorhombic,anditsunitcellhasdimensionsofa=12.15?,b=16.03?,andc=8.63?.Themineralhasatranslucentwhitecolor,anditslusterrangesfromvitreoustopearly.

Themostnotablepropertyofstudtiteisitsunstablenature.Themineralishighlyreactiveandcaneasilydecomposeintooxygenandwaterwhenexposedtolightorheat.Thispropertymakesstudtitechallengingtostudysincethemineralcandecomposebeforeaproperanalysisisconducted.However,thissamepropertyalsomakesstudtitepotentiallyusefulforvariousapplications.Forinstance,thedecompositionofstudtitecangeneratehugevolumesofoxygen,makingitanidealcandidateforuseinspacetraveltogenerateoxygen,fuel,orevenwater.
