Abstract
Pressure-induced transitions have previously been observed at room temperature in all the alkaline chalcogenides except MgS, MgO, BeS and BeO. This paper reports on studies to 96 GPa on BeS in which a phase transformation from the four-fold zincblende structure occurs at 51 ± 8 GPa to the six-fold nickel arsenide structure, which persists to the highest pressure studied. The equation of state is given.
