             abstract = "Porous materials are of significant interest due to their wide 
                         application in catalysis, separation, lightweight structural 
                         materials, biomaterials and other areas. Porous ceramics are 
                         produced within a wide range of porosities and pore sizes 
                         depending on the application intended. Porosity and pore size 
                         distribution can be carefully controlled by the choice of organic 
                         composite and the amount added. The material may have two types of 
                         pores: open and closed pores. The open pores, also called 
                         interconnected pores, are those which are in contact with the 
                         external surface of the material, being very useful for the 
                         manufacture of ceramic filters. A high number of closed pores are 
                         important for the manufacturing of materials used in thermal 
                         applications. There are many methods for obtaining porous 
                         ceramics, in general consisting in adding to the ceramic matrix 
                         organic particles, which volatilize during the first heat-up. The 
                         objective of this study was to produce ceramic composite 
                         nanostructure of alumina and yttria stabilized zirconia (Y-TZP) 
                         with micrometric pore sizes. The effects of ZrO2 additions in the 
                         mechanical properties of Al2O3 have been intensively investigated, 
                         due to the possible increase of the mechanical strength of this 
                         material. The organic particles used to create the pores were CMC 
                         and PVC. The microstructure of the porous ceramic samples obtained 
                         was evaluated considering the degree of sinterization of the 
                         nanoparticles, pores formation, porosity, specific surface of the 
                         pores and the distribution of the interconnecting pores.",
