Preparation method of pore controllable nano foamed ceramic
The invention provides a preparation method of pore controllable nano foamed ceramic. The preparation method comprises the following steps: uniformly mixing common Al2O3 powder with nano particles by using a high-energy ball mill to obtain compound powder; adding de-ionized water dissolved with a foaming agent into the compound powder and stirring at a low speed to obtain foamed slurry; pouring the foamed slurry into a mold and pressurizing to obtain a prefabricated body; heating the prefabricated body to remove a foaming agent; sintering the prefabricated body to obtain the product. With the adoption of the preparation method, the recovery rate of the solvent can be remarkably improved and energy consumption is saved. A nano material is added into a ceramic material, so that sizes of bubbles can be controlled after the material is foamed; the preparation method has the advantages of simple process, low cost, convenience for operation, no pollution and environmental friendliness and the like.
