Abstract

A combustion wave originating from an exothermic reaction between Mo and Si propagates through the reactants converting Mo-2Si mixture to Mosi2. X-ray analysis of the product confirmed that the product is single phase Mosi2 with no second phase or reactants when combustion synthesis experiments were carried out in argon. The oxygen content of the product was 0.22 wt.%. When the mixture was reacted under pressure in a hot press, the product obtained was also Mosi2, and a theoretical density up to 92% could be achieved. Heating of a mixture of Mo and Si with C leads to the formation of Mosi2 with a dispersed SiC phase.
