Estimating the term…
A ceramic composite material consisting of two or more crystal phases of different components, each crystal phase having a non-regular shape, said crystal phases having three dimensional continuous structures intertwined with each other, at least one crystal phase thereof being a single crystal. Further, by removing at least one crystal phase from this ceramic composite material, there is provided a porous ceramic material consisting of at least one crystal phase and pores, said crystal phase and pores having non-regular shapes and being three dimensionally continuous and intertwined with each other.
A ceramic composite material consisting of two or more crystal phases of different components, each crystal phase having a non-regular shape, said crystal phases having three dimensional continuous structures intertwined with each other, at least one crystal phase thereof being a single crystal, wherein said ceramic composite material contains impurities in a total concentration of not more than 1000 ppm, and is free of colonies, pores and boundary phases, said crystal phases being oxides selected from the group consisting of metal oxides and complex oxides of two or more metals.
A porous ceramic material consisting of at least one crystal phase and pores, said crystal phase and pores having non-regular shapes and being three dimensionally continuous and intertwined with each other, wherein said crystal phase constituting said porous ceramic material is free of colonies, pores and boundary phases, said crystal phase being an oxide selected from the group consisting of metal oxides and complex oxides of two or more metals.
