Porous ceramics are ceramic materials that have a network of interconnected pores. These pores can be used to store and release gases, liquids, or other substances. Porous ceramics are made by sintering a powder mixture, which results in the formation of a solid material with a porosity of 50% or more. The size, shape, and distribution of the pores can be controlled by adjusting the composition of the powder mixture and the sintering conditions.
