Title:StudyontheDispersionofNanoscaleZnOinCeramicGlazesbySodiumHexametaphosphate
Abstract:
NanoscaleZnOhasgainedsignificantattentioninthefieldofceramicglazesduetoitsuniqueoptical,electrical,andantibacterialproperties.However,achievinguniformdispersionofnanoscaleZnOinglazematerialspresentsasignificantchallenge.ThisstudyaimstoinvestigatethedispersioncharacteristicsofnanoscaleZnOinceramicglazesusingsodiumhexametaphosphate(SHMP)asadispersingagent.
Introduction:
Inrecentyears,nanoscaleZnOhasemergedasapromisingadditiveforceramicglazeformulations.Itspresenceinglazesenhancestheopticalproperties,electricalconductivity,andantimicrobialactivityofthefinalproducts.However,theuniformdispersionofnanoscaleZnOparticleswithinglazematerialsiscrucialforachievingthesedesiredproperties.Sodiumhexametaphosphate(SHMP)hasshownpromiseasadispersingagentfornanoscaleparticlesduetoitsstrongchelatingabilityandabilitytoformstablecomplexes.ThisstudyaimstoinvestigatethedispersionbehaviorofnanoscaleZnOparticlesinceramicglazematerialsusingSHMP.
ExperimentalMethod:
ThedispersionbehaviorofnanoscaleZnOinglazematerialswasinvestigatedusingacombinationofexperimentaltechniques.Firstly,thenanoscaleZnOparticlesweresynthesizedthroughasol-gelmethod.ThesynthesizednanoparticleswerecharacterizedusingSEM,TEM,andXRDtodeterminetheirmorphology,size,andcrystalstructure.TheglazeformulationswerepreparedwithvaryingpercentagesofnanoscaleZnOandSHMP.
ResultsandDiscussion:
TheresultsofSEMimagingrevealedthatwithouttheadditionofSHMP,nanoscaleZnOparticlesagglomeratedandformedlargeclusterswithintheglazematrix.However,withtheadditionofSHMP,thedispersionofnanoscaleZnOparticlessignificantlyimproved.SmallerparticlesizesanduniformdispersionwereobservedundertheinfluenceofSHMP,asevidencedbytheSEMandTEMimages.
TheXRDanalysisconfirmedthatthecrystalstructureofnanoscaleZnOremainedunaffectedbytheadditionofSHMP.TheXRDpeakscorrespondingtoZnOweresharp,suggestingthepreservationofitscrystalstructurewithintheglazematrix.
