Moulding tooling for the production of metallic moulded articles by casting, hot-, or cold-forming and method for producing such a moulding tooling

摘要

Tool mold is made completely from a homogeneous ceramic composition containing silicon carbide, silicon nitride, magnesium oxide, zirconium nitride, titanium nitride, zirconium diboride, titanium diboride and/or graphite. An Independent claim is also included for a process for the production of the tool mold comprising freezing the homogeneous ceramic composition after molding, drying, and hardening at a temperature depending on the composition of the ceramic composition.
