Aluminum titanate porous ceramic, preparation method thereof and porous medium burner
The invention discloses aluminum titanate porous ceramic, a preparation method thereof and a porous medium burner, and belongs to the technical field of ceramic. The aluminum titanate porous ceramic is prepared from slurry of raw materials through pyrolysis and sintering molding, and the raw materials comprise Al2O3, TiO2, a stabilizer, an adhesive, a dispersing agent and a solvent used for dissolving the adhesive, wherein the weight ratio of the Al2O3 to the TiO2 to the stabilizer is (50-70): (30-50): (1-10), and the stabilizer is at least one selected from the group consisting of magnesium oxide, magnesium carbonate, silicon dioxide, ferric oxide, cerium oxide, lanthanum oxide and yttrium oxide. The preparation method comprises the following steps of: immersing foamed plastic with pores into slurry of raw materials, coating the surface of the foamed plastic with slurry, drying and curing after coating, and sintering and molding after pyrolysis. The problem that existing aluminum titanate porous ceramic is poor in thermal shock resistance can be solved.
