Condensation Model Producing Crystalline or Amorphous Tetrahedral Networks

Fred Ordway 1

1 National Bureau of Standards, Washington 25, D.C.

Wire models of tetrahedral networks have been built up by a process representing condensation from a fluid, which yields amorphous structures unless a nucleus of crystalline structure is present initially. A random tetrahedral network of 300 units has been constructed for direct measurement of coordinates; the construction process is uniquely defined so that it may be possible to synthesize larger networks by use of a computer.
