Abstract

A method of forming a ceramic material or body comprises the steps of:--i) providing a water-containing mixture of raw materials ii) forming said mixture into a shape iii) removing water from said shape iv) firing said shape at a temperature sufficient to effect sintering and/or reaction of the raw materials and thereby form a ceramic material or body in which the raw materials include a hygroscopic polymeric material capable of retaining water in the mixture over, a range of temperatures above the boiling point of water. The hygroscopic polymeric material may be a so-called superabsorber, and the raw materials may comprise silicon carbide, graphite, sugar, and starch.
