PROBLEM TO BE SOLVED: To provide a porous base material made of ceramics which is excellent in various kinds of functions, such as air permeability, water absorption properties, water permeability, thermal insulating properties, absorptivity and soundproofing properties, has high strength and durability and is adequately used as environmental materials, such as building materials, vegetation base materials, adsorbent materials and water or air cleaning materials, with which desired porosity and desired shapes can be easily obtained, and a method for manufacturing the same and to obtain a base material for soil obtained by pulverizing the same. SOLUTION: A ceramic product molding formed by mixing at least carbon and/or organic material with ceramic raw materials and molding the mixture to a prescribed shape is heated and fired and is formed with a multiplicity of open cells and/or closed cells by carbon oxide (carbon dioxide and/or carbon monoxide) or expandable gas such as steam generated by firing and combusting of the carbon and/or organic material. |
