Abstract
This work examines general trends in the autowave synthesis of cast Mo-W-Si ceramics in a reactor at an elevated gas pressure using highly exothermic mixtures of molybdenum oxide, tungsten oxide, aluminum, and silicon. The results indicate that the gas (N2, Ar) pressure in the reactor and reactant ratio have a strong effect on the combustion process. We have obtained cast solid solutions with a controlled MoSi2: WSi2 ratio.
