Preparation method of fiber porous ceramic and fiber porous ceramic
The invention discloses a preparation method of fiber porous ceramic and the fiber porous ceramic, and relates to the technical field of ceramic production. The invention relates to a preparation method of fiber porous ceramic, which comprises the following steps: mixing: mixing ceramic fiber with a dispersant, adding a binder, and uniformly mixing to obtain fiber slurry; adsorbing and drying: adsorbing the fiber slurry on the surface of a mold under negative pressure to form a green body; performing vacuum drying on the green body to form a ceramic precursor; sintering: sintering the ceramic precursor to obtain fiber porous ceramic; the diameter of the ceramic fiber is 10-100 [mu] m, the tensile strength is greater than 500 MPa, and the length is greater than 10 [mu] m. According to the preparation method, the obtained fiber porous ceramic has uniform pores, the apparent porosity can reach 70% or above, most of the pores are open pores, the liquid guide performance of the prepared atomization core is improved by 30% or above compared with that of an existing porous ceramic atomization core, the adaptability of atomization liquid is greatly improved, and the phenomenon of core pasting is not likely to happen.
