Formulation of a Mathematical Process Model for the Foaming of a Mesophase Carbon Precursor

  • S. S. Sandhu (a1) and J. W. Hager (a2)


Mathematical equations have been formulated to guide an experimental effort to produce an open-celled mesophase pitch foam. The formulation provides an analytical description of homogeneous bubble nucleation and growth, diffusion of the blowing gas through the liquid to the bubble surface, and the average material thickness between bubbles. Implications of the formulation for the experimental production of mesophase pitch foam are discussed.
