CERAMIC SOLID-PHASE FOAM AND PROCESS FOR PRODUCING THE SAME

摘要

A ceramic solid-phase foam having closed pores with high porosity; and a practical process for producing the ceramic solid-phase foam. There is provided a ceramic solid-phase foam having closed pores defined by dense pore walls. Further, there is provided a process for producing a ceramic solid-phase foam, comprising the steps of incorporating a foaming agent in a ceramic matrix powder; carrying out integrated molding of the ceramic matrix powder and foaming agent to thereby obtain a molded item; and continually heating the molded item obtained by the integrated molding at a ceramic matrix sintering temperature to thereby sinter the ceramic matrix and effecting foaming of the foaming agent in the sintered ceramic matrix.
