It is well known that silicon, germanium and other diamond-cubic semi-conductors may transform to a metal when a pressure of the order of 100 kilobars is applied. This renders the detailed study of the transformation experimentally difficult. Grey tin transforms to the more common (white) metal allotrope at room temperature and pressure and so provides a means of studying readily this type of transformation. This paper describes the influence of pressure on the transformation characteristics of tin and dilute tin-germanium alloys.
