Abstract
A method for manufacturing molded articles from a ceramic composite structure, in particular from a combination of tri-silicon tetranitride and a metal silicide, in which gas pressures up to 100 bar are used and the sintering additive content can be reduced to under 10 mass percent. This inert gas sintering pressure method makes possible larger molding free spaces in complicated geometrical structures of the molded articles, in contrast to the known methods. In addition, the electrical properties of this composite structure can be regulated by adjusting a defined nitrogen partial pressure.
