Abstract

he progress in monolithic Si3N4 and SiC as well as in Si3N4/SiC-composites for structural applications is reviewed. The conventional processing including the powder synthesis, densification and microstructural design is discussed. The mechanical properties of the resulting silicon based non-oxide ceramics and their industrial applications as structural components are summarized. As an alternative route to fabricate Si3N4/SiC composites the hybrid processing utilizing the thermal conversion or organosilicon precursors to amorphous and polycrystalline multicomponent materials is described. The hybrid processed ceramics exhibit ultra-high temperature stability with respect to crystallization, oxidation and decomposition.
