Filtration combustion synthesis of porous sialon ceramics from Al-SiO₂-Si₂Al₄O₄N₄ mixtures in conditions of forced oscillation supply of nitrogen gas was explored. Forced infiltration of gas reactant was found to enhance the extent of nitriding and to decrease maximal combustion temperature due to kinetic restrictions on combustion reaction. The latter circumstance afforded for suppressing the melting and coalescence in combustion product and thus to retain its porosity.

振荡条件下强制过滤燃烧合成氮氧化物陶瓷

探索了在氮气强制振荡供给的条件下，由Al-SiO ₂ -Si ₂ Al ₄ O ₄ N ₄混合物过滤燃烧合成多孔硅铝氧氮陶瓷的方法。由于燃烧反应的动力学限制，发现气体反应物的强制渗透可增强氮化程度并降低最高燃烧温度。后一种情况可以抑制燃烧产物的熔化和聚结，从而保持其孔隙率。
