             abstract = "Porous ceramics are of great interest due to their numerous 
                         potential applications. The objective of the present investigation 
                         was to produce porous alumina with 3 mol % yttria-stabilized 
                         tetragonal zirconia (Y-TZP). This material will be used in cooling 
                         systems of satellites. To obtain the porous ceramics the direct 
                         foaming technique was used. This method is based on the 
                         preparation of a stable foam to which a slurry of alumina and 
                         zirconia is added. The mixture is then vigorously stirred for 
                         incorporation of air. The sintered ceramics were characterized by 
                         scanning electron microscopy, mercury porosimetry and thermal 
                         conductivity. The tests performed with the porous alumina-zirconia 
                         ceramic composite obtained by this method, showed low thermal 
                         conductivity values, high porosity and uniform microstructure with 
                         20-100 {\`{\i}}m open pores. The results show that the 
                         alumina-zirconia composites tested in this study have a potential 
                         for application in loop heat pipes of cooling systems of 
                         satellites.",
