The present invention relates to a preparation method of a porous ceramic, the porous ceramic, and a use thereof in the electronic cigarette. The method of preparing a porous ceramic includes: mixing amorphous silica, aluminum oxide and iron oxide uniformly to obtain a mixture; sintering the mixture at a temperature of 1000&#xb0; C. to 1400&#xb0; C. for 0.5 hour to 3 hours to obtain a precursor; grinding the precursor to obtain precursor powder; mixing the precursor powder, sodium silicate, and porogen uniformly to obtain a premix; mixing and extruding the premix with water to obtain a molded body; and heat preserving the molded body at a temperature of 200&#xb0; C. to 600&#xb0; C. for 1 hour to 6 hours, and sintering the molded body at a temperature of 700&#xb0; C. to 1200&#xb0; C. for 0.5 hour to 3 hours to obtain the porous ceramic.

Preparation method of porous ceramic, porous ceramic, and electronic cigarette

The present invention relates to a manufacturing method of a porous ceramic material, which includes the following steps: mixing a silicate material and a porogen to obtain a premix, wherein the silicate material includes sodium silicate and other compounds being at least one selected from the group consisting of oxides, nitrides, and carbides; drying the premix to obtain a silicate aggregate; mixing the silicate aggregate and an adhesive to obtain an injection molding material, wherein in a weight percentage, the silicate aggregate is in the range of from 50% to 60%, the adhesive is in the range of from 40% to 50%; injection molding the injection molding material to obtain a green body; and degumming and calcinating the green body successively to obtain the porous ceramic material. In the aforementioned manufacturing method of the porous ceramic material, the space-holder method is combined with the injection molding method, such that the obtained porous ceramic material has a high porosity, controllable pore sizes and good mechanical properties. In addition, compared with the dry pressing process, the use of the injection molding process can significantly improve the production efficiency, and is suitable for large-scale production.
