Material properties of silicon and silicon carbide foams Material properties of silicon and silicon carbide foams Jacoby, Marc T. 2005-08-18 00:00:00 ABSTRACT Silicon and silicon carbide foams provide the lightweighting element for Schafer Corporationâ s silicon and silicon carbide lightweight mirror systems (SLMSTM and SiC-SLMSTM).
Silicon carbide A has higher fracture strength, fracture toughness, and Weibull modulus as compared with silicon carbide B despite their similar microstructures. The enhanced mechanical properties of A are due to increased amount of intergranular fracture induced by a small change in the sintering additives that influence the grain‐boundary chemistry.
