The Effect of Pelletizing Pressure on SHS Synthesis of MoSi2

Article Preview

Abstract:

An experimental study on the preparation of molybdenum disilicide (MoSi2) was conducted by self-propagating high-temperature synthesis (SHS) from elemental powder compacts with different pelletizing pressures (0, 50, 100 and 200MPa). The composition of test specimens is Mo:Si = 1:2. The results showed that the propagation time of the reaction front, the density of the combustion products, the particle size and the morphology of MoSi2 were significantly influenced by pelletizing pressure of the reactant compact. In addition, all the samples obtained with different pelletizing pressures were single-phase MoSi2.
