Abstract: The effect of Additives (Si3N4, C, La2O3) on the microstructures and the mechanical properties of RBSN is investigated in this paper. The action regularity on the sintered bodict of these additives and the suitable amount of them to improve the properties of sintered body are obtained. The relation between the density composition of sintered body and its strength is dis-rnsscd.

Key words: additive, reactive sinter, silicon nitride
