| titleOfInvention | Preparation method of zirconia porous ceramic |
| abstract | The invention relates to a preparation method of zirconia porous ceramic, which comprises the following steps: step 1: putting zirconia powder and carbon fiber into a container, adding a proper amount of water, stirring and mixing, adding a foaming agent and a foam stabilizer in the stirring process until bubbling is uniform, and then adding a binder to obtain a mixed material; step 2: pouring the mixed material into a forming die, and naturally airing and forming to obtain a green body; and step 3: putting the green body into a closed box, vacuumizing, then filling butane and oxygen to normal pressure, standing, igniting by electronic fire after 1.5-3 hours to enable the butane to burn, and obtaining a perforated green body after the burning is finished; and 4, step 4: and sintering the blank with the opening at high temperature to obtain the zirconia porous ceramic. The carbon fibers are connected in a cross way to form a network framework which is used for firmly supporting the zirconia powder and other materials, so that the toughness and the strength of the ceramic are improved; the foam stabilizer is introduced to control the time of foam breakage, so that the porous material with uniform pore diameter and compact arrangement is obtained, and the preparation process is green and environment-friendly. |
