The invention discloses a kind of barium titanate foamed ceramicses and preparation method thereof.Using organic binder bond, organic rheological agent and organic dispersing agent as auxiliary agent, deionized water is solvent, and nano barium phthalate is ceramic raw material, after mixed grinding, forms the slurry with certain solid content；Pretreated polymeric sponge is impregnated in slurry after hanging processing, through drying, obtains hanging ideal and the barium titanate foamed ceramics green compact without plug-hole, then barium titanate foamed ceramics is obtained through sintering.Foamed ceramics provided by the invention is in 3 D stereo network skeleton structure, and skeleton is made of the single pure barium titanate ceramics of chemical composition.It is integrated with the excellent dielectric properties of barium titanate and foamed ceramics high porosity, low-gravity feature, while has high intensity.The preparation method of barium titanate foamed ceramics provided by the invention has the characteristics that simple for process, applicability is wide, is suitable for industrialized production. |
