Abstract: A porous ceramics is provided to be manufactured at low temperature in a low cost and be usable as important parts in many industries. A porous ceramics is prepared by mixing an inorganic material, a glass powder of zinc borosilicate-based glass ceramics, and at least one component selected from inorganic pore-generating aids comprising carbon, graphite, and fly ash, and heat-treating the mixture at low temperature lower than 900 ‹C. The inorganic material comprises at least one component selected from alumina, cordierite, forsterite, zeolite, fly ash, kaolin, mica, and talc. The glass powder of zinc borosilicate-based glass ceramics forms a crystal phase by a reaction with the inorganic material in a borosilicate-based glass system. Further, the porous ceramics comprises the 30-40 vol.% of inorganic material.
