摘要：

Effect of template size ratio on porosity and mechanical properties of porous zirconia ceramics were investigated using two different size (similar to 8 mu m and similar to 50 mu m in diameter) of polymethyl methacrylate-coethylene glycol dimethacrylate (PMMA) microbeads as sacrificial templates. Porosity of the porous zirconia ceramics increased with decreasing the template size ratio (8 mu m:50 mu m) whereas the compressive and flexural strengths of the porous zirconia ceramics increased with increasing the template size ratio. By controlling the template size ratio, sintering temperature and sintering time, it was possible to produce porous zirconia ceramics with porosities ranging from 57% to 69%. Typical flexural and compressive strength values of porous zirconia ceramics with similar to 60% porosity were similar to 37 MPa and similar to 85 MPa, respectively.
