<p>The method for the production of a material having a reduced sintering tendency is characterised in that an admixture phase of 0.1 50 vol. % is added to the starting material prior to sintering, said phase comprising at least one pyrochlore compound from the group consisting of (La<sb>2</sb>Zr<sb>2</sb>0<sb>7</sb>, Gd<sb>2</sb>Zr<sb>2</sb>0<sb>7</sb>, d<sb>2</sb>Zr<sb>2</sb>0<sb>7</sb>, Sm<sb>2</sb>Zr<sb>2</sb>0<sb>7</sb>, u<sb>2</sb>Zr<sb>2</sb>0<sb>7</sb>, La<sb>2</sb>Hf<sb>2</sb>0<sb>7</sb>, or a mixture). The following substances can be used as suitable starting materials: partially and fully stabilised zircon oxide, perovskites, spinels, mullites, cerium compounds or also defective fluorite compounds which have regularly, significantly reduced sintering activities by adding an admixture phase. Said characteristic enables said material to be used in an advantageous manner as a heat-insulating layer.</p> |
