Abstract:
1. A porous body comprising: a ceramic body produced by calcining a molded body comprising a mixture including a plurality of skeleton particles and a plurality of pore forming particles comprising an organic polymer and a plurality of inorganic particles, wherein the molded body is calcined in a temperature range sufficiently high for a sufficient duration such that the skeleton particles directly bind with each other and form inner surfaces and void spaces and that the inorganic particles of the pore forming particles form a plurality of inorganic compound components present on the inner surfaces formed by the skeleton particles directly bound with each other and comprising an inorganic compound, each of the skeleton particles comprises a ceramic selected from the group consisting of a nitride ceramic, a carbide ceramic and an oxide ceramic, the plurality of inorganic particles comprises at least one inorganic material selected from the group consisting of a nitride ceramic, a carbide ceramic, an oxide ceramic, a metal and a metal compound, and the ceramic of the skeleton particles is different from the inorganic compound of the inorganic compound components.
