Abstract
A process of producing a porous ceramic by mixing a ceramic powder, a polymerizable unsaturated compund, an emulsifying agent, and water with stirring to provide an inverted emulsion, radical-polymerizing or redox-polymerizing the polymerizable unsaturated compound in the inverted emulsion to cure the inverted emulsion, and, then, drying and firing the cured product thus obtained. The porous ceramics obtained by this invention are useful as filters, adsorbents, catalyst carriers, refractory heat insulating materials, sound absorbers and building materials.
