Method of sintering metal-dispersed reinforced ceramics

A method of sintering metal-dispersed ceramics. The synthesis and sintering of ceramics is simultaneously carried out utilizing the reaction heat generated when at least one metallic element selected from groups III, IVa, Va and VIa groups of the Periodic Table is combined with at least one non-meta...

Zusammenfassung:A method of sintering metal-dispersed ceramics. The synthesis and sintering of ceramics is simultaneously carried out utilizing the reaction heat generated when at least one metallic element selected from groups III, IVa, Va and VIa groups of the Periodic Table is combined with at least one non-metallic element such as B, C, N and Si, in amounts such that the metallic powders are present at a ratio higher than the stoichiometric ratio, without the input of external heat or preliminary heating of the ceramics, at temperatures substantially lower than the usual sintering temperature, to obtain a sintered ceramics matrix with unreacted metal distributed therein.
