The influence of fiber additives on the combustion process and composition of Sialon obtained by the SHS method

The effect of fiber additives (basalt and polypropylene) on the process of nitriding by self-propagating high-temperature synthesis (SHS) of a powder mixture consisting of silicon, aluminum and microsilica was investigated. The effect of fiber additives on the combustion wave front propagation rate and the maximum combustion temperature, as well as on the nitrogen content, phase composition and structure of combustion products was studied. Optimum fiber additives suitable for use as reinforcing components of β-SiAlON obtained by the SHS method were determined. Ill. 4. Ref. 14. Tab. 1.
