Abstract
In order to improve a method for the production of structural ceramics and/or functional ceramics consisting of silicon carbide ceramics, with which a porous precursor body is produced from a cellulose-containing material, the porous precursor body is converted into an open-pored carbon body by means of pyrolysis and the open-pored carbon body is converted into silicon-containing carbide ceramics, in particular, silicon carbide ceramics as a result of infiltration of silicon-containing materials, in such a manner that the structural ceramics and/or functional ceramics as well as the components produced therefrom can be produced with properties which are as reproducible as possible it is suggested that at least cellulose-containing powder be used as starting ingredient for the production of the precursor body.
