Conventional preparation of porous ceramics often hard to accurately control the porosity of the samples. In this paper, by improving the foaming method, the foaming process is placed in the limited space of the ball mill tank, and YSZ porous ceramics with different porosity are obtained by changing the amount of slurry. Initial results showed that the porosity of the sample varies linearly with the increasing of addition of slurry. From the microscopic morphology, it can be seen that the increase in slurry content will reduce the number of pore with little changed size, which lead to the decrease in porosity. Therefore, with simple calculation YSZ porous ceramics with 85%, 80%, 75%, 70%, and 65% porosity can be obtained using the method of foaming in limited space by ball milling.
