Analysis of Sintering of a Composite with a Glass or Ceramic Matrix

A recently developed theory for sintering of bimodal powders is applied to a composite where the matrix is either a glass or a ceramic. The filler phase is assumed to be rigid and nonsintering. It is shown that glass‐matrix composites should have predictable sintering behavior which follows the rule of mixtures, but ceramic‐matrix composites are expected to be more difficult to sinter, and their sintering behavior may deviate considerably from the rule of mixtures, even at low concentrations of the filler phase.
