| 英文摘要 | The feasibility of mechanical-activation (ma) assisted combustion synthesis of silicon nitride with the ptfe as additive was demonstrated using silicon/ammonia chloride as reactants at nitrogen pressure below 2 mpa. the addition of ptfe enhances the reactivity significantly, which promote the nitridation of silicon in the outer layer of the reactant compact. the increase of ptfe content in the green mixture stimulates the increase of a-silicon nitride content in the surface of the reactant compact. the equiaxed silicon nitride grain with a-phase content up to 77.7% was obtained when ptfe addition was 4%. the residual silicon left in the center of the combustion synthesis product was completely nitridated by further heat treatment at 1300 degrees c for 1 hour in nitrogen atmosphere. the temperature difference between the centre and the edge of the sample was responsible for the difference in both phase composition and morphology of the product. |
