Abstract
A porous material of desired porosity and pore size is made by mixing a piculate material and fungible beads that are thermally decomposable until the desired distribution is attained; compacting the mixed material and beads to form a green body that has sufficient strength to be handled where the beads are undecomposed; and compacting and heating the green body to fuse the material particles and to decompose the beads to gas.
