The influence of the mechano-chemical activation on the fabrication of porous ceramics from black paper sludge ash (BPSA, waste materials) was studied using planetary ball mill to obtain activated powder. Mechano-chemical process is used to modify properties of materials, enhance the reactivity of materials and produce advanced materials. After mixing activated powder with alkaline solution (KOH) and kept until completely solidification in steam oven, so that porous ceramics were formed by generation of gas. The physical properties of the porous ceramics were investigated using SEM, X-ray CT and mercury porosimeter. Based on the results, mean particle size and the visible pore size of solidified specimen were decreased with increasing of rotation speed and treatment time. The porous structure can be controlled by generation of gas. These were used to explain the formation of the graded porosity.
