Atomic force microscopy (AFM) was used to image the surface of ceramic powder compacts that contained polymer and solvent during drying. Topographical information was continuously collected as a function of drying time. Surface changes were directly observed during imaging. Surface crystals appeared on damp zirconia sheets after drying, subsequently contributing to secondary flaws in the form of holes in fired ceramic products. In cases where few surface crystals were observed in the green stage, fine grain size and high strength were observed after firing. The fired material was viewed via AFM and shown to be directly related to the drying process that was observed earlier.
