Abstract

A method of making a dried porous ceramic body having interconnected surface pores and interior channels. The body is formed by extrusion from a paste and is irradiated with microwave radiation to heat it for an initial period at a rate of at least 15.degree. C./minute, after which the irradiation is reduced so that the body is heated at a rate of at most 1.degree. C./minute. Heat loss from the external surface of the body, during heating, is resisted.
