This work presents techniques to generate densely packed diamond-like
particles, for example, as present in a metal matrix composite of Al, Cu, or Ag
reinforced with single crystals of synthetic diamonds; as intended to be used
for heat sinks or very efficient thermal conductors, spreaders, etc.
Two different ways are described to predict the thermal conductivity of the
composite: line tracing and surface-averaged Hasselman and Johnson.
The effects of diamond volume fraction, size and, in particular, shapes on the
composite thermal conductivity are discussed.
