Abstract:
In this report the theoretical and experimental morphology of p-xylene crystals growing from both the pure melt and a mixture of about 31% o-xylene and 69% of p-xylene will. be discussed. All above mentioned morphologies agree quite well with each other. The experimental forms found are {100}, {001}, {20(1) over bar} and {110}. The actual roughening temperatures can be scaled, using the non-observed stable forms, and regarding them as being rough at the actual growth temperature. Also a comparison of the morphology of naphthalene and p-xylene is made.
