Abstract

See full text

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.
