Method for the production of ceramics

Method for the production of structural ceramics and/or functional ceramics at least partially consisting of silicon-containing carbide ceramics, comprising:

• producing a porous precursor body from at least a cellulose-containing powder and a binding agent as starting ingredients, the starting ingredients having a grain size of less than 100 μm,
• converting the porous precursor body into an open-pored carbon body by means of pyrolysis, and
• converting at least a portion of the open-pored carbon body into silicon-containing carbide ceramics as a result of at least partial infiltration of silicon-containing materials into said open-pored carbon body,
• wherein after hardening of the binding agent the precursor body is stored in a manner inert to moisture.

Method for the production of structural ceramics and/or functional ceramics at least partially consisting of silicon-containing carbide ceramics, comprising:

• producing a porous precursor body from at least a cellulose-containing powder as a starting ingredient,
• converting the porous precursor body into an open-pored carbon body by means of pyrolysis, and
• converting at least a portion of the open-pored carbon body into silicon-containing carbide ceramics by siliconization as a result of at least partial infiltration of silicon-containing materials into said open-pored carbon body,
• the siliconization being carried out in a nitrogen atmosphere having a pressure in the range of between approximately 0.1 mbar and approximately 10 mbar.
