The Effect of SiC Powder Size at Reaction Bonded SiC Composite Fabricated by a Molten Si Infiltration Method

다국어 초록 (Multilingual Abstract)

Reaction bonded silicon carbide(RBSC) composite for heat-exchanger was fabricated by molten Si infiltration method. The raw
materials with variable particle sizes were used in this experience. The finer the particle size in sintered silicon carbide was the more
increasing 3-point bending strength and fracture toughness. As the adaptable particle sizes had been occupied interstice arising from
packing sample, the mechanical properties were increased. In the PCS1-1 sample, the 3-point bending strength and fracture toughness
were 323MPa and 4.9MPa·m1/2, respectively.
