Приведены исследования по изучению влияния фракции SiO 2 в исходной шихте на параметры синтезируемого при твердопламенном горении в реакторе конечного продукта. Установлен фазовый состав, и определена микроструктура продукта. Конечный продукт представлял собой порошок, состоящий из равноосных частиц сиалона состава Si1.84 Al0.16 O1.16 N 1.84 и галоидной соли Na3 AlF 6 с небольшим количеством Al2 O3 , Al, Si, AlN.

Studies are presented to study the influence of the SiO2 fraction in the initial charge on the parameters of the final product synthesized during solid-flame combustion in the reactor. The phase composition has been established and the microstructure of the product has been determined. The final product was a powder consisting of equiaxed particles of sialon with the composition Si1.84Al0.16O1.16N1.84 and the halide salt Na3AlF6 with a small amount of Al2O3, Al, Si, AlN.
