Preparation method for zirconium oxide porous ceramic plate
The invention discloses a preparation method for a zirconium oxide porous ceramic plate. The preparation method comprises the following steps: adding a hydrochloric acid solution in a yttrium oxide solution to generate a yttrium chloride solution; mixing the yttrium chloride solution, a zirconium oxychloride solution and polyethylene glycol, and dropwise adding an aqueous ammonia solution to generate yttrium hydroxide precipitate and zirconium hydroxide precipitate; washing the yttrium hydroxide precipitate and the zirconium hydroxide precipitate with water, filtering, then cleaning with absolute ethyl alcohol and drying to obtain a zirconium oxide ceramic precursor; dispersing the obtained zirconium oxide ceramic precursor in the absolute ethyl alcohol, drying and calcining, and then carrying out ball milling to obtain zirconium oxide ceramic powder; mixing the zirconium oxide ceramic powder, a pore former and a tackifier, and then preparing to obtain a porous plate green body; and calcining the porous plate green body, and preparing to obtain the zirconium oxide porous ceramic plate. According to the preparation method for the zirconium oxide porous ceramic plate, through the pore former and the tackifier, the green body is prepared, and is calcined again to obtain the zirconium oxide porous ceramic plate with relatively high mechanical performance.
