Title:PreparationofPorousCeramicsUsingGypsumHemihydrateasaFoamingAgent:AStudyonitsProperties.
Abstract:
Porousceramicsarewidelyusedinvariousindustriesduetotheiruniquepropertiessuchaslowdensity,highspecificsurfacearea,andexcellentthermalstability.Inthisstudy,weinvestigatedtheuseofgypsumhemihydrateasafoamingagenttoprepareporousceramics.Theeffectsofdifferentpreparationparametersonthepropertiesoftheresultingceramicswerestudied,includingtheamountofgypsumhemihydrate,sinteringtemperature,andholdingtime.Thepreparedporousceramicswerecharacterizedusingvarioustechniquessuchasscanningelectronmicroscopy(SEM),X-raydiffraction(XRD),andBrunauer-Emmett-Teller(BET)analysis.Theresultsdemonstratedthatgypsumhemihydratecanbeeffectivelyusedasafoamingagenttoprepareporousceramicswithdesirableproperties.
1.Introduction:
Porousceramicsareaclassofadvancedmaterialswithawiderangeofapplicationsinfieldssuchasfiltration,catalysis,andthermalinsulation.Typically,porousceramicsarepreparedbyincorporatingafoamingagentintotheceramicmatrix,followedbyheattreatmenttoremovethefoamingagentandsintertheceramicparticles.Gypsumhemihydrate,alsoknownasplasterofParis,isawidelyavailableandinexpensivematerialthathasbeenusedasafoamingagentforvariousapplications.However,itsapplicationasafoamingagentinthepreparationofporousceramicsisrelativelyunexplored.Inthisstudy,weaimtoinvestigatetheuseofgypsumhemihydrateasafoamingagenttoprepareporousceramicsandevaluatetheirproperties.

2.1Materials:
Themainmaterialsusedinthisstudywerecommercial-gradeceramicpowdersandgypsumhemihydrate.
2.2PreparationofPorousCeramics:
Theporousceramicswerepreparedbymixingtheceramicpowderswiththedesiredamountofgypsumhemihydrateasafoamingagent.Themixturewasthencompactedintothedesiredshapeandsinteredatdifferenttemperaturesforvaryingdurations.Aftersintering,thefoamingagentwasremovedbyleachingwithwater.
