Abstract
The invention provides a method of producing a porous ceramics material. The method comprises preparing a slurry by dispersing a ceramics raw material in a medium, filling the slurry in a container, inserting the container in a given direction into a cooling medium having a temperature not higher than the freezing point of the slurry such that the slurry freezes unidirectionally from one end side, drying the frozen slurry to give a green body, and firing the green body.
