Abstract
This paper presents the results of combustion synthesis of porous Si3N4 based ceramics from
silicon powders, with fine α-Si3N4 and BN powders as diluents, under high nitrogen pressure. The effect
of addition of BN on the morphology is investigated. The results revealed that the strength decreased and
the porosity increased with the addition of BN, which is strongly depended on the final morphology of the
products.
