text: The porosities of the pore forming materials for a porous body 1A, 1B and 2C are obtained by determining the components of the organic polymer and those of inorganic particles for a pore material using, for example, gas chromatography, fluorescent X-ray analysis, or the like and then calculating the respective densities using a specific gravity bottle.
text: The porosity is obtained using the two volume values.
text: In the sintering (necking between particles) owing to the recrystallization of silicon carbide powder per se, shown in JP-A-6-182228, porosity is obtained but the silicon carbide powder per se is allowed to give rise to recrystallization; therefore, a very high firing temperature need be used which invites a high cost and, moreover, a material of high thermal expansion coefficient need be fired at a high temperature which invites a reduced yield in firing.
