Influence of Pelletizing Pressure on the Particle Size and Morphology of MoSi2 Prepared by Self-propagation High-temperature Synthesis
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 in molar ratio (corresponding to the Si content in 66.7 at.%).The results shows,that the density of the combustion products,the particle size and the morphology of MoSi2 are significantly influenced by pelletizing pressure of the reactant compact.In addition,all the samples obtained with different pelletizing pressures are single-phase MoSi2.
