Abstract
The pore forming material for a porous body of the present invention comprises organic polymer particles and inorganic particles. As the embodiment thereof, there may be mentioned one having a structure in which the inorganic particles are contained in the organic polymer particles, and an aggregate body of the organic polymer particles and the inorganic particles. The inorganic particles may be inorganic micro-balloons, and the organic polymer particles may be organic micro-balloons.
Claims19
A pore forming material for a porous body, comprising:
- an organic polymer component which thermally decomposes during a sintering of a green porous body;
- and
- an inorganic component,
- wherein the organic polymer component comprises a plurality of organic polymer particles, the inorganic component comprises a plurality of inorganic particles, the organic polymer particles and the inorganic particles comprise a plurality of aggregated bodies of the organic polymer particles and the inorganic particles, and each of the aggregated bodies has a volume ratio of the organic polymer component to the inorganic component in a range of about 0.1 to about 250, and the plurality of aggregated bodies formed by filtering and degassing a mixture comprising the organic polymer particles and the inorganic particles such that each of the aggregated bodies has an average particle diameter in the range of about 20 to about 60 μm.
