Abstract

Using a diamond cell the 14-kbar and 17-kbar transitions in single rhombs of calcite have been observed and photographed under hydrostatic pressures. The nature of these reversible transitions are described with respect to observed transition planes. A single crystal of HNO₃ in equilibrium with its own liquid was grown at a pressure of approximately 4 kbar and a solid–solid transition was observed at 8 kbar and room temperature.
