Preparation of Porous Si3N4 Based Ceramics by Combustion Synthesis

Abstract:

Article Preview

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.
