| 发明名称 | Porous ceramic and method for producing same | ||
| 摘要 | A porous ceramic for which any decrease in water permeability can be suppressed over a long period of time. A porous ceramic is composed of a porous ceramic sintered body produced by molding and sintering a mixture containing a clay, wherein a surface portion of the porous ceramic sintered body has been removed by grinding. The mixture preferably contains a foaming agent. | ||

| 主权项 | 1. A porous ceramic composed of a porous ceramic sintered body produced by molding and sintering a mixture comprising a clay, wherein either one or both surface portion in the thickness direction of the porous ceramic sintered body has been removed by grinding, wherein pores formed in the porous ceramic are continuous pores that are mutually interconnected, wherein the degree of grinding is a depth of 0.5 to 5 mm from the fired surface of the porous ceramic sintered body, wherein the mixture comprises a foaming agent, and wherein the foaming agent is a slag with a blend amount from 10 to 80% by mass. | ||
