ABSTRACT:
There is provided a method for manufacturing a porous ceramic structure, including: firing a formed body containing ceramic particles and a combustible powder functioning as a pore former, and burning off the combustible powder to obtain the porous ceramic structure. As the combustible powder, porous resin particles having an average particle diameter of 10 to 50 μm and a porosity of 50 to 90% are used. The method for manufacturing a porous ceramic structure can inhibit the combustible powder functioning as a pore former from being smashed upon mixing/kneading a forming raw material and suppressing an excess heat generation upon firing and can manufacture a porous ceramic structure having a stable porosity with a good yield.
