Zirconium pyrophosphate multiphase porous ceramic material based on foaming method and preparation method thereof

The invention relates to a zirconium pyrophosphate multiphase porous ceramic material based on a foaming method and a preparation method of the zirconium pyrophosphate multiphase porous ceramic material. According to the technical scheme, the preparation method comprises the following steps: mixing ammonium dihydrogen phosphate, zirconium oxide and rare earth oxide, and carrying out ball milling, drying, heat treatment and crushing on the mixed material I; mixing the crushed powder with deionized water, mixing the mixed material II with an alkali metal phosphate dispersant, and carrying out ball milling to obtain a mixture III; then mixing magnesium hydroxide, tin hydroxide and niobium hydroxide to obtain a mixture IV; mixing and ball-milling the mixture III and the mixture IV, adding an anionic foaming agent, and stirring to obtain foaming slurry; and adding the gelatin solution into the foaming slurry, stirring, pouring into a mold, standing, drying, heating to 1000-1300 DEG C, and preserving heat to obtain
