Three Dimensionally Ordered Microstructure of Polycrystalline Zirconia Ceramics with Micro-Porosity Chang, Myung Chul;
In order to make a highly ordered three-dimensionally macro-porous structure of zirconia ceramics, porogen precursors PMMA beads were prepared by emulsion polymerization using acrylic monomer. The monodisperse PMMA latex beads were closely packed by centrifugation as a porogen template for the infiltration of zirconium acetate solution. The mixed compound of PMMA and zirconium acetate was dried. According to the firing schedule, dry compacts of PMMA and zirconium acetate were calcined at to obtain micro-, macro-, and meso- structures of polycrystalline zirconia with monodispersed porosity. Inorganic frameworks composed of were formed and showed a three Dimensionally Ordered Microstructure [3DOM] of ceramics. The obtained skeleton was calcined at . The 3DOM skeleton showed color tuning in solutions such as deionized [DI] and/or methanol. The monodispersed crystalline micro-structure with micro/meso porosity was observed by FE-SEM.
