Conclusions

It is shown that the character of variation of Φin and Φout with free silicon concentration in base plates in the wetting of self-bonded polycrystalline silicon carbide by silicon is in qualitative agreement with Johnson and Dettre's model [6], which links the wetting behavior of two-phase base plates with their energy heterogeneity.
