Abstract: Barium titanate foam ceramics and a preparation method thereof are disclosed. An organic binder, an organic rheological agent and an organic dispersing agent are used as auxiliaries; deionized water is used as a solvent; nanometer barium titanate is used as a ceramic raw material; and all of same are mixed and ground so as to form a slurry with a certain solid content. A pretreated polymer sponge is impregnated into the slurry for slurry coating treatment and then dried to obtain a barium titanatefoam ceramic blank with an ideal slurry coating and without blocking holes, and same is then sintered so as to obtain a barium titanate foam ceramic. The foam ceramic has a three-dimensional network skeleton structure, and the skeleton of the foam ceramic is composed of pure barium titanate ceramic of a single chemical composition.
