| 英文摘要 | Combustion synthesis (cs) of si3n4 with the addition of polytetrafluoroethylene (ptfe) was carried out at a relatively low n-2 pressure of 2 mpa. it was found that the additive ptfe promoted the nitridation of si. the alpha-si3o4 contents in the periphery of the combustion-synthesized products showed great dependence on the contents of ptfe added in the reactants, which reached 77.7 wt.% with 4 wt.% ptfe addition. the residual silicon in the center of the combustion-synthesized products could be completely nitrided by further heat treatment at 1300 degrees c for 1 h in n-2. the temperature difference between the center and the edge of the samples was responsible for the discrepancy in both phase composition and morphology of the products.
