Novel porous oxide ceramic and preparation method
The invention discloses a novel porous oxide ceramic. A formula for the novel porous oxide ceramic comprises the following raw materials in percentage by mass: 41 to 48% of nickel oxide, 27 to 34% ofyttrium-stabilized zirconia and 25% of a pore-forming agent, namely graphite powder. The invention also discloses a preparation method of the novel porous oxide ceramic. The preparation method comprises the following steps: S101, adding a dispersing agent, namely polyacrylic acid into ultrafine mixed powder of the nickel oxide and the yttrium-stabilized zirconia, and carrying out ball milling in aball mill for 8-10 hours; S102, adding the pore-forming agent graphite powder, carrying out ball milling for 10 hours, then adding an adhesive, namely polyvinyl alcohol and a plasticizer, namely polyethylene glycol, and carrying out ball milling for 12 hours; and S103, granulating slurry obtained in the step S102 through centrifugal granulation and drying equipment, and carrying out sintering after isostatic cool pressing to obtain the novel porous oxide ceramic. By changing the ceramic formula, the produced novel porous oxide ceramic is endowed with more properties, the effects of structuralsupport and a carrier are achieved, the porous ceramic material is endowed with a catalytic effect, and the service life of the produced novel porous oxide ceramic is prolonged.
