Notes:
In this study, SHS process has been employed to fabricate porous MoSi2 material with electric-resistive heating capability through the control of pore size. The preform for SHS reaction was consisted of molybdenum powder with different sizes and silicon powder with different contained quantity. The size of the MoSi2 particles thus formed was determined by the generated heat of combustion, not by the size of molybdenum powder. However, the pore size of MoSi2 composite was proportional to the particle size of molybdenum powder. That is, the coarser the molybdenumpowder used, the larger the formed pore size. Based on these results, the porous MoSi2 composite could be fabricated with a desired pore size. By orienting the porous molybdenum disilicide-based material in the form of pore size gradient, porous materials used for filters with improved dirt-holding capacity can be manufactured
