Title:OptimizationofProcessParametersforthePreparationofNanoscaleBismuthPowderusingOrthogonalExperimentalDesign
Abstract:
Nanotechnologyhasrevolutionizedmanyfields,includingmaterialsscienceandengineering.Theoptimizationofprocessparametersiscrucialtoachievehigh-qualitynanoscalematerials.Thispaperfocusesontheoptimizationofprocessparametersforthepreparationofnanoscalebismuthpowderusingorthogonalexperimentaldesign.Thisdesignallowsforthesystematicinvestigationofmultipleparameterssimultaneouslytoidentifytheoptimalcombinationthatyieldsthedesiredoutcome.Throughthisstudy,theeffectsofvariousparameters,suchasreactiontemperature,reactiontime,concentrationofreactants,andstirringspeed,willbeinvestigatedtodeterminetheoptimumconditionsforthepreparationofnanoscalebismuthpowder.
