摘要： The present invention relates to microporous ceramic materials, and the production method thereof, which can be suitably used in various structural materials, high-temperature filters, electrode materials, preform materials for infiltration, etc., wherein said method comprises the steps of: producing molded bodies by homogeneously mixing a starting material of polymer ceramic precursor powder, and then forming the same; saturating the same by introducing fluid of a non-critical state to said molded bodies in a pressure vessel; super-saturating the fluid of a non-critical state saturated to molded bodies by adjusting pressure in said pressure vessel; forming micropores in said molded bodies by evolving said fluid of a non-critical state from said molded bodies by heating said molded bodies; hardening said molded bodies having micropores; and carrying out pyrolysis by heating said hardened molded bodies. Accordingly, the present invention allows easy control of pore characteristics (e.g., pore size and pore size distribution) suitable to target materials by adjusting pressure at a non-critical state, and without requiring additional processes or devices, the present invention allows production of microporous ceramic materials of enhanced strength, having uniform size and homogeneous distribution of pores over the entire material.

摘要： One aspect of the present invention pertains to an apparatus for forming a rigid foamed cementitious core within a plurality of article shells. In general, the apparatus can be comprised of a shell bank for retaining a plurality of article shells and comprising a sled and a plurality of reinforcement shells, a filing station for delivering a gas-entrained cementitious material, and a pump. The gas-entrained cementitious material cures to form a rigid foamed cementitious core within each article shell in the plurality of article shells.
